Why yous should trust the states

I've spent the past several months scrolling through scores of masks online, poring over documents from the CDC's National Constitute for Occupational Condom and Wellness (NIOSH) and the FDA, and puzzling over footling certification slips one-half-written in Chinese (a babyhood's worth of Saturday morning Chinese school has not helped). I've washed this as function of my reporting for Wirecutter's guide to cloth face up masks but also for personal reasons: My husband, a teacher, and child have been attending school in person since September 2020, earlier vaccines were available, and nosotros have older parents we've been trying to go along safe.

More than than a year subsequently, we adults are hoping to get our booster shots soon, my eleven-yr-old is finally vaccinated, and we're eager to spend time with family and friends, schedule doc visits, and grab upwardly with all the other activities we've missed. Withal, unless we're outdoors, I personally adopt to outfit myself and my family with highly protective masks that I tin trust.

For this guide, I tracked down legitimate respirators and masks, as well as reliable retailers that sell them. My husband and I tested the masks for fit, comfort, and (for those who want to layer up) compatibility with our cloth-mask picks. I also sent the masks to a panel of Wirecutter staffers with different face shapes, and collected their feedback. As well consulting five scientists, I've interviewed five manufacturers, iii importers, two retailers, an e-commerce expert, and two government agencies. In all, I've so far assessed 25 respirators and 14 surgical-way masks.

What is a medical-style mask, and do you demand 1?

The term "medical-manner mask" refers to the types of masks you typically see in health-intendance settings. These include respirators, such as those labeled N95 (designed to meet US standards), KN95 (Chinese standards), KF94 (Korean standards), and FFP2 (European standards), likewise as surgical-fashion masks—the pleated variety with ear loops or ties that typically come in boxes of fifty or so. Consisting of loftier-efficiency filter layers, all of these mask types are designed to protect the wearer in high-run a risk situations. (Cloth masks, in contrast, were initially intended to protect other people from the wearer, though depending on their materials and design, they tin can also work the other way effectually.)

If you're spending time among others indoors, visiting a hospital or clinic, or caring for a COVID-xix–positive person (or someone who is vulnerable to a severe case of COVID-19), you may consider wearing either a respirator mask or a surgical-manner mask modified to grade a amend seal or layered under a well-plumbing equipment cloth mask. In fact, a CDC newspaper reported that securing a surgical mask to the face (by knotting the ear loops and tucking in the sides, equally shown in this video, or by adding a well-fitting cloth face mask over information technology) can potentially decrease your exposure to perhaps infectious tiny airborne droplets called aerosols past well-nigh 95%, which is likewise about how well respirators are expected to perform.

This level of filtration on medical-style masks (assuming they're genuine) is improve than what y'all tin go from virtually all masks made from only material, said Linsey Marr, a professor of engineering at Virginia Tech who is an skilful in the scientific discipline of aerosols. In fact, when Wirecutter commissioned cloth-mask filtration-efficiency testing, filter-less, double-layer material masks filtered (at a flow rate like to what happens with normal talking volume) around 47% of 0.5-micron particles at all-time. (Those with incorporated filters, however, such as the Enro Tech and Happy Masks Pro, filtered similarly to N95s.) If you're non vaccinated, Marr "highly recommends" bolstering your well-fitting fabric mask, whether past wearing a surgical-blazon mask beneath it or including a good filter inside it. Vaccinated people may choose to do this equally well, depending on the circumstances.

N95 vs. KN95, KF94, FFP2, and surgical masks

Constructed with multiple layers of nonwoven textile, an N95 respirator blocks out at least 95% of particles every bit small as 0.1 micron in bore. Surgical N95 respirators offering the added benefit of besides having passed tests for such factors every bit fluid resistance, biocompatibility, and flammability. All legitimate N95 masks are canonical past NIOSH as respirators; surgical N95 models take undergone boosted NIOSH testing to meet specific FDA requirements.

N95 masks fasten snugly to your face with two bands that get around the back of your head. As with cloth face masks, some people find bands to exist easier to adjust than ear loops—you can play around with knots and positioning to create a adept seal. However, an N95'south elastics tend to be tighter than those on cloth masks, which some wearers might discover suffocating. Some N95 masks, like Wirecutter's picks for dealing with smoke and dust, have valves for easier exhalation, but considering they let unfiltered air escape, they are non useful in preventing the spread of the coronavirus.

KN95 masks (China's N95 equivalent) should block out 95% of 0.3-micron particles; KF94 and FFP2, 94%. All are fabricated with similar layers of high-filtration, nonwoven materials. KN95, KF94, and FFP2 are internationally sourced respirators and therefore don't undergo the NIOSH approval process. Earlier in the pandemic, with N95 respirators in short supply, some of these masks—if they met sure criteria—were FDA-cleared for workers in health-care settings under an emergency use authorization (EUA). That authorisation has since been revoked (PDF) due to a replenished supply of N95s, but the FDA suggests that these previously authorized respirators (such as our pick, the Powecom) exist redistributed for use in nonmedical settings.

Unlike N95 masks, these other respirator masks typically have ear loops instead of headbands. People often encounter good filtration but a bad fit when shopping for a KN95. The same goes for N95 masks that aren't customized (as they typically would be in a infirmary setting). A January 2021 PLOS One article on mask-fit bug reported that a KN95 was a poor fit for all seven written report participants, while the v N95 masks in the experiment did little better—declining to fit 4 out of vii subjects. Fifty-fifty a bit of extra fatty in the chin or a few millimeters in the width of the nose can take an impact on a respirator'due south fit, the authors noted.

Loretta Fernandez, PhD, associate professor of civil and environmental engineering at Northeastern University, found that a poorly plumbing equipment KN95 may block 0.three-micron particles only every bit effectively every bit a poorly fitting surgical mask—at around 72% efficiency instead of the promised 95%-plus. This level of performance may be problematic for people working in the ICU but possibly less so for someone doing a quick run to the post office. Still, from an economical perspective, it's pointless to spend the extra money on a KN95 only to have it work equally finer a much cheaper mask. Fernandez, who has been assessing masks (PDF) since the kickoff of the pandemic, noted an easy fix that a dentist shared with her: Past cutting the ear loops on a KN95 mask and reattaching them to form headbands, the dentist was able to achieve a secure enough fit to nudge the filtration back up past xc%.

Surgical masks are medical devices regulated by the FDA. These masks are designed to forestall fluid from penetrating the mask (from, say, splattering every bit a result of a medical procedure) and potentially harming the wearer. Because they don't fit close to the face, they're not designed to protect the wearer from inhaling small, potentially infectious particles. Still, in gild to gain FDA clearance, either through 510(yard) or the agency's emergency use authorization, surgical masks undergo testing to meet voluntary consensus standards set by ASTM International (formerly the American Society for Testing and Materials)—and those standards include achieving a level of filtration efficiency. Level 1 indicates that the mask blocks out 95% of particles at 0.1 to 5 microns in bore at certain flow rates following some other set of challenges. Levels ii and 3 betoken at least 98% for the same particle-size range.

Medical-grade masks should be fluid resistant and should keep their shape in the rain better than most cloth masks. Regardless of which type of mask y'all manage to get your easily on, even so, you won't come anywhere close to the stated filtration values in real life unless you secure a perfect seal to your face around the entire perimeter of the mask. "More often than not speaking, if you're fogging up your glasses, it'southward non a perfect seal," said Hana Akselrod, assistant professor of medicine in the partitioning of infectious diseases at George Washington University School of Medicine. (If you don't habiliment glasses, take a big exhale with your mask on—if you feel a puff of air on your skin near the edges of the mask, you lot need a tighter fit.)

Our favorite respirator masks

We set out to identify and detect accurate disposable respirator masks, from reputable sellers, that are reasonably priced and well built. We're continuing to test these masks for fit and condolement, and we will be trying other options as they go available.

Kimberly-Clark N95 Pouch Respirator

What nosotros like: This duckbill-shaped mask is a NIOSH-canonical N95 respirator manufactured in the US. It's also our favorite because it's the but 1 of its type that really fit our testers well, and it felt surprisingly comfortable. Thank you to its soft, flexible construction, the Kimberly-Clark N95 Pouch Respirator should fit nearly people. Kimberly-Clark is an established manufacturer of diapers, tampons, and other personal-intendance products that humans employ against their bodies, and at present the company has leveraged that engineering science into expanded mask offerings (earlier the pandemic, Kimberly-Clark's manufacturing employees had used this mask in-house). Because it's a nonmedical respirator, this mask is not tested to protect you from potential splatter of actual fluids.

Soft headbands that easily knot and stretch over diverse positions on the head form a good seal and are enough comfortable for long-term habiliment. A more than cavernous cut (nearly an inch wider on each side compared with the typical respirator) means more filtered air to exhale in. In our experience, a long, sturdy nose-span wire helped minimize glasses fogging, too. I was able to place the lower band college on my caput to prevent air from escaping around my chin (a pain bespeak for me with other respirators). This mask doesn't experience the easiest to breathe through—but that suggests some caste of filtration efficiency. ("I'm always suspicious of masks that accept little or no breathing resistance to them," said Christian L'Orange, the banana research professor of mechanical engineering who ran our cloth-mask filtration test at Colorado State University.) The Kimberly-Clark mask closes absolutely apartment without the need for you to pinch the nose wire closed, as y'all take to with many other foldable masks, and at around $1 a mask, it's as well the least expensive NIOSH-canonical N95 we've seen so far.

What we don't like: This mask looks ridiculous, particularly compared with sleek textile masks. "Our initial focus was offer functioning and comfort over form," said Rob Hughes, vice president of PPE at Kimberly-Clark Professional. He added that the company is currently evaluating boosted designs. Note, too, that this mask is truly for sometime use: With too much wear and tear or rough usage, the bands can rip, and the nose-span wire on top can become unstuck.

WellBefore WB-Due north-200 N95 Respirator Mask

What we like: Many NIOSH-approved N95s and headband-way KN95s we've tried were either too big or besides tight. The sturdily constructed WellBefore WB-Northward-200 N95 Respirator Mask likewise felt large on some of our panelists, but a bit less and so, and more of import, it didn't feel suffocating despite creating a good seal. This is partly due to the plastic brackets on either side of the mask, which allow you to tighten the headbands as necessary. But it's also cheers to the ample clearance the mask allows over the nose and mouth, which offers plenty of room for filtered air to circulate. A foam strip over the nose-bridge wire provides some cushioning.

What we don't like: "This is a lot of mask," several testers commented, noting the WellBefore's plastic and foam features, wide headbands, and girth. This mask is also more than twice the toll of our other respirator picks, the lighter but odd-looking Kimberly-Clark N95 and the piece of cake-on, easy-off but less-adjustable Powecom KN95. These respirators, sold in packages of five or more, also come individually wrapped (which some people may observe beneficial for tossing in a bag or glove box, though others may find it unnecessary).

Powecom KN95 Respirator Mask

This mask is currently experiencing shipping delays.

What we like: This formerly FDA-emergency-authorized KN95 mask offers some variety—you can choose from ear loops or headbands, as well equally black or white. Nosotros bought Powecom masks directly from the importer and distributor through Bona Fide Masks, a legit site that'south part of Ball Chain Manufacturing, the largest manufacturer of ball-concatenation-related products in the world. (You know, the strings of metallic beads that go along keys together, switch lamps on and off, and hold military dog tags.) Thank you to its brawl-chain business, the company already had reliable sources in China, who helped information technology make it touch with a reliable mask maker, Guangzhou Powecom. (Recently, Bona Fide Masks became the exclusive distributor of Powecom KN95s in the US and Canada.)

Powecom has been effectually since 2009 and is a recognizable name in Prc for making masks, even before the pandemic. Its KN95 was FDA-cleared nether the agency's emergency use authorization during the N95 shortage. When Chinese authorities updated the KN95 standard this summer, we commissioned Colorado State University'south Center for Energy Development and Wellness to verify that the Powecom mask sold by Bona Fide Masks maintained its high filtration efficiency. And it did: With a perfect seal, the mask offered more 99% filtration efficiency for 0.5-micron-bore particles drawn through a chamber at a rate of 15 liters per minute (similar to the rate that a person would exhale when talking at normal volume). We similar that the mask's fasteners are sturdily attached (more so than most) and that they knot hands for adjustment. Slightly rounded, as opposed to apartment, they're somewhat gentler on the ears, also. We also like that you tin can cull to buy every bit few equally ten masks in a pack (though you can order as many every bit x,000). The dimensions were neither besides big nor too modest for nearly of our testers, even so the mask also accommodated one tester who has a beard (though, of class, facial hair inherently lessens a mask's seal).

What we don't like: As some readers have pointed out, the Powecom design'south ear-loop elastics can experience uncomfortably snug. If that'southward the case for you, try gently pulling on them to loosen them upward a bit before wearing the mask. Smaller faces may have the opposite issue, at least with the ear-loops version of this mask: The straps may be too loose to create a close fit. But that has been the case with almost all the medical-style masks we've tried—without string locks and malleable fabric, respirators just aren't every bit adaptable as cloth masks. Knotting the ear loops helped me block the air from escaping at my chin but somehow increased the fog on my glasses. In contrast, headbands provide a snugger fit, though one tester found that the headband version of this mask was too tight for condolement (and strongly preferred the ear-loops version).

Every bit of late Jan, the Powecom masks were experiencing shipping delays. Bona Fide Masks told u.s. that information technology had recently ramped upwardly its production and customer service departments in response to the demand, and that new orders would no longer be charged until items ship. The company hopes to return to its usual aircraft timeline of 1 week past early February. For existing orders, rush orders, or concerns, the company advises sending a text to the number in your order confirmation.

Our favorite surgical-mode masks

Surgical masks are less expensive and less thick than N95 designs and other respirators, simply because they tend to gape at the sides, they crave some adjustments for optimal protection. Equally the CDC recommends, you can knot the ear loops and tuck the sides (this CDC video shows you how) or add together an adjustable cloth face mask (like one of our picks) on top. You tin also exercise both. We've tried 14 surgical-style masks over the past few months, and for the most role, the differences have been barely discernible. The DemeTech DemeMask Surgical Mask and the Medline ASTM Level 1 Process Face Mask with Ear Loops are our favorites because, more than other masks we've seen that are reliably in stock, they're a good value for the level of protection they offer.

DemeTech DemeMask Surgical Mask

What nosotros like: Most dispensable pleated masks experience and office about the aforementioned, but the DemeTech DemeMask Surgical Mask is FDA 510(1000)-cleared and meets ASTM Level 3 standards, as it's capable of blocking 98% of particles as small as 0.1 micron (assuming a expert seal). Nosotros like its exceptionally soft ear loops, which feel knitted and don't dig into the ears as most other elastics practise. The loops are likewise firmly attached, so when you're putting this surgical mask on or taking it off, the fasteners are less likely to popular off (as we've institute with some cheaper models). With its soft edges, the DemeMask is like shooting fish in a barrel to knot at the ear loops and tuck at the sides (video) for a secure fit. We also similar that it comes in a small size, which might work for some bigger kids, and in a necktie version, which may be especially helpful for people who wear hearing aids.

What we don't like: The DemeMask is costlier than most pleated masks you can find online or in a drugstore, though its price is roughly in line with that of masks offering similar filtration credentials, such every bit the CVS Health Surgical Face Mask, a former choice. If you're using these masks just occasionally, you lot tin opt instead for a pack of 10 for $7.50. You might too find promotions as a beginning-time buyer on the DemeTech site.

Medline ASTM Level 1 Process Face Mask with Ear Loops

What we similar: We're always downward for a bargain, and this box of 50 is bachelor for the best price we've seen so far for an FDA-cleared surgical mask. As its name indicates, the Medline ASTM Level 1 Procedure Face Mask with Ear Loops meets ASTM Level one standards, which ways it blocks at least 95% of particles measuring 0.one micron in diameter or larger. That's 3% less than the Level iii DemeTech masks can block, but unless you're a health-care provider in a high-chance medical setting, that's not much of a difference. Medline makes its own masks only also partners with other FDA-cleared manufacturers to avert stock shortages, a visitor spokesperson told united states. The Medline mask's ear loops are slightly larger than those on the DemeTech mask (and most other surgical-type masks we've seen); this allows them to stretch over wider faces with less tension on the ears. The extra length of elastic also ways you can easily seal side gaps past knotting the ear loops and tucking in the sides (video).

What we don't like: Except for their larger ear loops and FDA clearance, the Medline masks are fairly run-of-the-factory. Their inner lining isn't particularly tissue-like as with the CVS version nosotros tried, nor are the ear-loop elastics as soft or firmly attached equally those on the DemeTech mask. Medline says information technology partners with other manufacturers too the one we link to above, just it does not disclose them. You lot can confirm that its other overseas manufacturing partners are indeed FDA 510(k)–cleared by typing the company name (found on the Document of Conformity, a slip of paper enclosed in the box) into the FDA's device database.

What to await forward to

We're trying the boat-shaped Evolve Together KN95, which comes in a range of colors and has a stylish, nonmedical look. So far, four testers accept establish the mask light and comfortable, with a sturdy withal pliable olfactory organ-span wire and soft ear loops. However, the ear loops of one batch nosotros received separated easily when we tugged them in different directions, and in our experience this mask has collected more condensation than our picks. Nosotros haven't assessed the mask's filtration capabilities withal, simply nosotros volition study dorsum after further evaluation. We're also testing the NIOSH-approved 3M Aura Particulate Respirator 9205+ N95, which is boat-shaped and now more widely available than before in the pandemic. Then far we've found it to exist one of the sturdiest masks we've tried—complete with cushioning across the nose-span wire, aplenty breathing room, and comfortable headbands that create a practiced seal. We are also slated to test the Armbrust USA-Fabricated KN95 Mask, which Armbrust says is manufactured past a company that makes N95s, also as the DemeTech D95, a mask made from the same material and on the same machines every bit DemeTech's N95s (simply it's welded with ear loops instead of caput bands).

How nosotros picked and tested

Photograph: Sarah Kobos

Searching for a reliable respirator or surgical-mode mask for a decent price, specially earlier in the pandemic, has been the most hard shopping feel I've ever had. It's like trying to observe the terminal Lego Star Wars Advent calendar three weeks before Christmas—but infinitely worse. Aside from navigating retailers that accept long sold out or are price-gouging, you're as well contending with fraudulent sellers, fraudulent products, or both: The CDC reports that about sixty% of KN95 masks sold in the United states are imitation. What's more than, there are sizing issues. Oh, and whatever you buy is typically nonrefundable.

Almost ii years afterward, the shortages take eased up, but that doesn't make finding the right mask any easier, peculiarly when information technology comes to KN95s. Yes, there's the counterfeit issue. But also, KN95 and surgical-way masks don't always fit very well. Equally Loretta Fernandez, an associate professor of civil and environmental engineering at Northeastern Academy in Boston, explained, "There'southward nada magical about a KN95. The edges still need to form a skilful seal against the face up for it to exist protective." The truth is, any medical-style mask—no matter how superior the filtration—doesn't practise much better than a quality cloth mask if it allows most of the air you're breathing to become effectually it rather than through it. Proper fit is critical.

As for disposable pleated masks, every neighborhood store and online vendor seems to sell them these days, but not all of them are actually surgical masks—just surgical-fashion, which is why they're often a tertiary or half the price of actual authorized surgical masks. The packaging on almost simply says "face mask," in which case you tin can't look the masks to filter like the kinds of masks that health-care workers wear in hospitals. In fact, Colorado State University'southward Christian L'Orangish—who has tested thousands of masks, including our picks—told us that the most egregious fails accept come from surgical-manner masks every bit opposed to respirators. Some accept exhibited a mere 20% filtration rate on small particles (about the same as many of the filterless cotton masks we tested for our guide to material face masks), though well-nigh of them accept demonstrated a slightly less shocking 70% to 80% charge per unit. Others have appeared to be missing layers altogether, he said. I way to detect a false is to hold information technology top side up under a dripping faucet: If the aerosol soak in instead of completely beading up, it's not a existent surgical mask, which past definition should have some level of water resistance.

We decided to kickoff out with retailers we trust, including Costco, CVS, and Office Depot. We also perused business-news articles online about The states-based companies that are manufacturing or selling masks, or both. Virginia Tech'southward Linsey Marr suggested buying directly from a reputable supplier whenever possible, non just grabbing any y'all find from a tertiary-party seller (the fewer middlemen, the smaller the gamble of mischief). So we checked out each company's e-commerce site and confirmed that each respirator or surgical mask of interest is included in one of the following:

• NIOSH maintains a listing of approved N95 respirators.
• The FDA's Personal Protective Equipment EUAs (emergency use authorizations) Appendix A list of surgical masks and foreign respirator manufacturers indicates that the manufacturer submitted exam reports demonstrating that the product met certain performance standards, including filtration efficiency, and that the FDA recognized information technology. Although health-care workers are now advised to once once more utilize merely NIOSH-approved designs, these masks are even so helpful in everyday settings.
• The FDA has a database of devices that have received 510(k) clearance.
• NIOSH's International Respirator Assessments evaluate US-sold, foreign-made respirators merely; nosotros look for good results on these tests. Although these tests aren't the same equally NIOSH approval, they do requite mask buyers a sense of the quality of the materials used.

Sometimes cantankerous-checking wasn't possible until we received the masks and found the product qualification certificate—the pocket-sized slip of paper in the packaging that includes the details almost the production and its manufacturer, which is usually one-half written in the language of the country the mask comes from. Nosotros as well reached out to some of the manufacturers or the sellers to sympathise the vetting or manufacturing process, especially if we couldn't discover the manufacturing visitor on any of the in a higher place lists.

For masks sold on Amazon, we confirmed with the manufacturer that we had a legit link to the product it was selling, and if nosotros couldn't attain the manufacturer (and if the mask was sold out everywhere except Amazon), we checked that the mask was both sold and shipped directly by Amazon. Although this factor limits your choices peradventure unnecessarily, every bit Kathy Cummins, head of marketing and analytics at Swivel Global, pointed out, we similar the assurance that a specific inventory of the product has been vetted by Amazon itself, and we appreciate that aircraft past Amazon cuts out the middleman and ensures prompt delivery. A caveat: The "aforementioned" mask sold by the aforementioned visitor tin differ depending on the retailer. For example, masks manufactured past the Chinese company Winner Medical that we bought on Amazon consisted of thinner, less-soft mask fabric than we found on the Winner Medical masks once sold past CVS, despite their having the same product name ("Medical Face Mask"), standard certification (ASTM Level ane), and listed materials ("non-woven 66%; cook blown, 34%") on the certification slips. Winner Medical confirmed to united states that it designs masks co-ordinate to a client'southward specifications while still ensuring the same protective effects.

One time we tracked downwardly several masks that nosotros concluded were really medical-form, our job had only but begun. We too needed to assess each mask in terms of fit and comfort—something far too individual for anyone to judge in a general sense. Withal, we're doing our best by distributing masks to a diverse group of nine panelists (two of whom are my husband and me).

As with our guide to cloth face masks, we'll continue to add to this listing of trusted respirator and surgical-manner masks as new and better options become available. Stay tuned for future updates.

How to reuse disposable face masks

Rubber comes get-go during a pandemic, which is why some experts are urging people to opt for dispensable masks with high filtration efficiency when possible. But the environmental impacts of a far larger population—beyond but wellness-care workers—donning masks made of nonrecyclable materials are significant. The pandemic generates upwardly to an estimated 7,200 tons of medical waste every 24-hour interval, a big portion of which is disposable face masks, according to the authors of a July 2021 study published in BMJ Open up. Decontaminating an N95 mask for multiple wears could reduce the amount of pandemic-related environmental waste product by 75% or more compared with disposing it afterwards each use, the authors add. That'southward why they've been working on developing a fully reusable, easily sterilizable silicone face mask suitable for health-care workers.

For everyone else, whose risk of exposure is generally far less, there are more sustainable choices, including reusable cloth masks with high filtration efficiencies such equally the Enro Tech or Happy Masks Pro, both picks in our guide to the best cloth face masks. Another pick is to wear dispensable masks more than in one case.

Yes, outside of the wellness-care setting, most people can safely reuse some dispensable face up masks. While health-intendance workers are typically advised to throw out their masks after a unmarried use, that'due south not e'er necessary for everyone else. This is especially true given the presence of additional layers of protection (such equally vaccines, social distancing, and good ventilation). Every bit a result, experts told united states, it often makes sense to reuse disposable masks—but carefully, taking cues from what wellness-care workers did during the N95 respirator shortage earlier in the pandemic.

Every bit the CDC notes, a mask tin can be reused later it has been stored in a paper bag for a few days. (SARS-CoV-ii, the virus that causes COVID-nineteen, has an expected survival time of 72 hours.) Even better, consider exposing a worn mask to sunlight, as doing so may help speed up the virus-inactivation procedure. In my home, I accept 7 newspaper numberless, each 1 marked with a day of the week, lined upward by a sunny windowsill. At the end of each 24-hour interval, I driblet my used mask in its corresponding purse. After five days (because I prefer to exist extra safe), I move the mask to an eighth bag, which I've marked "gear up to wear."

The CDC guidance, intended for health-care personnel in situations much riskier than what I feel in my twenty-four hour period-to-twenty-four hour period routine, notes that masks shouldn't be used more v times. Merely masks worn past most people in relatively low-adventure situations could probably be worn for considerably longer. "There'southward no time limit for how long a filter will work," explained Ron Shaffer, old inquiry primary at the National Personal Protective Technology Laboratory at NIOSH. He advises throwing away a mask when it's soiled or worn out, when it no longer fits well, or when information technology's difficult to breathe through. When in dubiety, throw it out. For further details, see our additional guidance on safely reusing masks.

Other medical-style masks we like

These masks stood out from the remainder of the competition because of the positive response nosotros received from a relatively broad swath of panelists, as well equally their high performance in our filtration-efficiency testing. They aren't every bit affordable as our current picks—but depending on your needs, yous may find them worth the extra expense.

4CAir AireTrust Nano Mask

This mask is currently out of stock. You lot tin can sign upward here for inventory alerts.

The 4CAir AireTrust Nano Mask is one of the thinnest KN95-type masks we've tried, thanks to its patented nanotechnology. Less like padding and more similar newspaper, the mask feels light on the face and offers arguably better breathability. One panelist wore it to pilates: "My confront didn't sweat underneath it because it'southward so lite," they said. "After 2 minutes, I forgot information technology was in that location." Because this mask hasn't even so undergone FDA clearance, nosotros did our ain filtration testing in collaboration with researchers at Colorado State and confirmed that, equally advertised, it has a filtration efficiency of 99% for particles every bit small as 0.five micron. Respirators more ofttimes than not come in one size, so we like that this i comes in three: small (for kids), medium, and large. The modest size fifty-fifty has cord stoppers in the ear loops. All of our panelists plant a size that fit them well, though some establish the mask more than snug effectually the olfactory organ (hence no glasses fog) than at the chin. We would make this mask a option except that, at more than $3 apiece, it's much pricier than our picks from Powecom and Kimberly-Clark (each around $1 per mask). But nosotros'd splurge on a v-pack for $17.50 for the infrequent situations where we might especially appreciate a mask that's lighter than most, such as a lengthy flight or a long dr.'s visit.

Kyungin Flax KF94

Because of KF94 masks' more than structured "boat" shape (a horizontal rectangle that tents up to secure itself over the olfactory organ bridge and chin), they're somewhat harder to adapt, and our panelists had different opinions on which fit best. But if you'd like to try one, the Kyungin Flax KF94 is one of the more affordable models nosotros've tried. Like almost KF94s, which didn't arrive in the US until after in the pandemic, the Kyungin Flax mask was never FDA-cleared for emergency employ for medical workers. So, in collaboration with Colorado State, we filtration-tested the mask ourselves—and found information technology to block 99% of particles as small as 0.v micron.

Overall, near KF94s feel thinner than the N95s and KN95s nosotros tried (except for the Kimberly-Clark mask we recommend and the 4CAir AireTrust Nano Mask we also like), and their boat-similar shape provides arguably more-reliable clearance over the nose and mouth. The Kyungin Flax is no different. Still, this mask comes in just 1 (rather big) size—which made it harder for some of our panelists to achieve a solid seal. If y'all adopt a KF94 mask and have a narrower chin or smaller face, you might have ameliorate luck with masks from Dr. Puri, Blue, or Etiqa. Wearing the mask on a cold winter 24-hour interval, we've too noticed it collecting more condensation at the inner layer than our picks.

More NIOSH-approved, NIOSH-assessed, or FDA-authorized masks worth because

The masks in this section have either undergone the stringent NIOSH testing required to earn an official N95 designation or submitted the necessary testing results and paperwork for FDA clearance, whether via a now-revoked emergency use dominance or the 510(k) process.

Folded flat, near cone-shaped respirator masks—similar the Powecom KN95—measure most half dozen inches vertically unless otherwise noted. Still each one fits differently depending on how it's angled around the nose and mentum, how pliable the material is, and whether the fasteners are ear loops or headbands.

Some of these masks may be out of stock.

In our experience, the BYD Intendance KN95 Respirator sealed well, thank you to its more easily adaptable headband fasteners, simply the olfactory organ-bridge wire could slide downwardly the nose and block the airway a scrap. This may non exist the case for people with higher nose bridges, though—so, as we've mentioned, we'll go on evaluating this mask with a diverse panel of testers and update this guide accordingly. The fasteners have ridges, which meliorate grip. This KN95 had been listed nether the FDA'southward now-revoked emergency use authority Appendix A.

BYD Care's nonmedical N95, sold at Office Depot, is NIOSH-approved and is no longer flagged as "reserved for healthcare workers and first responders." Compared with the make'due south KN95 respirator, this mask has shorter fasteners, which make for a more snug fit, and a somewhat stouter contour, which allows for more room above the olfactory organ and rima oris. However, 1 tester described it as "really painful to wear," though that's also the reason why she "trusts" it for doctor'southward appointments at a hospital. (Pre-vaccination, my husband wore this N95 to the New York City public school where he has been pedagogy in person; he arrived dwelling to find "reassuring" imprints on his face. Not everyone feels the same style about an ultra-snug fit.)

Florida-based wound-care company DemeTech, the maker of our surgical-mask pick, launched its respirator production early on in the pandemic. We similar that the NIOSH-approved DemeTech respirators come in two designs (cup and foldable) and each in regular or small size. With their sturdy, ridged headbands, y'all can play with the positioning of these respirator masks for a better fit. My married man and I tried the regular-size foldable masks, and they stood up slightly less high off our faces, peculiarly near the nose, compared with other masks nosotros tried. But they formed a decent seal and, as other panelists noted, also felt lighter. At $75 for a box of twenty, they're as pricey equally another lightweight respirator we tried, the 4CAir AireTrust Nano Mask. If you need just a few, a pack of five is available for less than $20.

Measuring just 5 inches vertically from summit to lesser, the Korean-made and NIOSH-approved Dobu Mask 500 N95 is likely all-time for people with smaller faces; it barely covered my husband's mouth, and other testers on our panel equated it to wearing a bra cup or hamburger bun on their face. (It fit two panelists perfectly, though.) A bracket keeps the fabric off the face, and a ring of soft, cotton fiber-tee-like material surrounds the nose and mouth while somehow creating a comfy seal without a nose-wire bridge. Plastic adjusters on each side easily help you tighten the ridged headbands. You can press this mask in half, merely because of the bracket, it doesn't stay folded similar the others on this listing. It's as well somewhat thicker overall. We've confirmed that the mask, available on Amazon (marked "sold and shipped by Dobu Mask"), is legitimate. As expected, the actress hardware makes for a more expensive mask (10 for $twoscore) compared with about we've considered.

The much cheaper, foldable NIOSH-approved Dobu Mask 201 N95 fits snug like the BYD Care N95 but with slightly less clearance over the olfactory organ and mouth, and arguably a more than gentle bear upon. Unlike the BYD Care N95, "they don't dig into my eyes," said i panelist. If you go through N95s on a regular footing (similar my husband, who wears 1 to teach in-person classes every mean solar day), the Dobu masks can get pricey (at this writing, they're near $twoscore for a pack of 25 on Amazon). For a more affordable, similarly shaped mask, consider the Powecom KN95 (sold in a headband selection at virtually $i per mask). Its elastics feel a bit looser just still create a secure—and mostly more comfortable—seal, co-ordinate to our panelists.

The Dr. Puri Micro-Dust Protection Mask isn't NIOSH-canonical, just a June 2020 filtration test run by NIOSH (PDF) on samples sent to the agency reported that it blocked more than than 99% of 0.3-micron particles. It fit nearly of our panelists, though some testers thought it saturday too close to the mouth despite its typical KF94 rectangular boat shape. Some testers said the masks smelled funny ("dusty," described one panelist); nosotros'd take these masks out of the packaging and allow them air out before wearing. We confirmed that the mask sold via this Amazon link (labeled "sold by Dr. Puri Official") is legitimate, and it'south at a slightly lower toll than nosotros've seen elsewhere.

FLTR sells the NIOSH-approved manufactured-in-China N95 Round Respirator, which we oasis't tried. Considering that it'south sold only in bulk (100 masks), nosotros thought information technology was cost-prohibitive for people who'd similar to brand sure their mask fits earlier going all-in.

The Harley Commodity N95 Particulate Respirator, sold at Bona Fide Masks, may be a better fit than most for people with larger faces. It measures about a quarter-inch greater vertically, from tip to tip, compared with the half dozen-inch Powecom KN95—so it hits the corner of my optics. I can breathe amend in it, though, since the olfactory organ portion (complete with a nose pad) has a less-steep slope. If it'south the correct size for your face, you're probable to go a decent seal with the ridged, sturdily affixed, elastic headbands. And the mask is NIOSH-canonical (see Guangzhou Harley).

The United States Mask Particulate Respirator N95 is manufactured domestically and NIOSH-canonical. Similar in size vertically to the Harley Commodity mask (about 6¼ inches), it hits my lower eyelids. Its effectually-the-head bands are piece of cake to knot for a proficient seal, bold the mask fits your face. It also costs less (effectually $45 for xx masks) than most other bifold-style N95s, which typically run about $3.fifty or more per mask.

The Honeywell DF300 N95 Particulate Disposable Respirator is similar to the BYD KN95: It too offers a more snug fit for small faces than the Harley Commodity and United States Mask models. A piece of cream cushions its sturdy, pliable nose-span wire. It'south a bit pricier than our picks just cheaper than almost others on this list. It's also NIOSH-approved.

The Makrite 910 is a duckbill-shaped N95 like the Kimberly-Clark mask we recommend, but it is non nearly equally comfortable. The thick textile proved much less breathable for our testers, and the headbands looked and felt like thick, albeit smooth, safe bands. The nose-bridge wire is cushioned by a foam strip, withal, and this model is NIOSH-approved. You tin play around with the bands for a meliorate seal, but overall nosotros found this mask to be quite restrictive and suffocating.

We were quite excited about the NIOSH-canonical RespoKare N95 Respirator Mask'southward pretty blue colour and comfy nose-bridge absorber, just some panelists found that the ear straps snapped off easily. While the big size was likewise large for many panelists (it might be proficient if you've determined that nearly masks are also pocket-sized for you), the medium size was much smaller—and, in fact, too small for me. These masks accept a strong vinegary olfactory property out of the package, and they cost considerably more than our picks.

We liked the CVS Health Medical Face Mask when we tested it, but consistent stock issues keep it from existence a pick in this guide. This mask has a strikingly softer underlayer—much softer than that of most other surgical masks we've tried, including our selection from DemeTech. The version we tried met ASTM Level 2 standards, which meant it could filter out at to the lowest degree 98% of 0.ane-micron particles, assuming a perfect seal; withal, we've noticed that the masks are at present labeled as coming together ASTM Level 1 standards. The generous ear loops should help this mask fit wider faces, and they're easily knotted for narrower ones.

More masks (that aren't FDA-authorized or NIOSH-approved)

Simply because a mask isn't cleared past these agencies doesn't necessarily mean it performs poorly, though information technology's hard to know for sure. FDA clearance and NIOSH approval can have many months and can cost a good amount of money—some companies decide non to bother, while others take submitted the paperwork only are nonetheless awaiting a decision.

Some of these masks may be out of stock.

Every bit with many K94s we tried, the Blue KF94-3D Mask fit some of our panel testers well but left gaps on others. Our panelists agreed, however, that it felt lightweight. According to its packaging and authorized seller Exist Good for you (a longtime trusted source for Korean imports), this mask is approved by the Korean Ministry building of Food and Safety; for confirmation, we reached out to the makers of Blue masks, besides as to the Korean Ministry building of Food and Condom, but we didn't receive responses. We elected not to send the Blue mask out to Colorado Country for filtration-efficiency testing because, besides lacking wide fit appeal, information technology costs more than than the Dr. Puri and Kyungin Flax KN94 masks we prefer—and it is considerably more expensive than our picks.

The Etiqa Airway Round Mask is neither FDA-cleared nor NIOSH-canonical, but co-ordinate to its packaging and seller Be Healthy, it has been canonical by the Korean Ministry building of Food and Safety. (The colorful variations accept not undergone the Korean Ministry of Food and Prophylactic approval procedure, though the materials are similar.) Nosotros didn't include this mask in our filtration testing, nor did we investigate it further, because also many panelists complained of fit bug (information technology didn't grasp the chin very well). And many testers noted that information technology had a stiff scent out of the package that didn't fade apace. It sells for a rather pricey $4 a mask and is currently out of stock.

The FLTR95 Sealing Confront Mask is no longer available. When nosotros tested it, it was sold at Costco in a pack of 100. Its third-party lab documentation demonstrated filtration results similar to those of KN95s but blocked out the mask manufacturer's proper name, citing proprietary data; in improver, the manufacturer's proper name wasn't translated on the certification skid. These masks, which come up in white or blackness, are like in shape (measuring 6 inches vertically, tip to tip) and elastic to the Powecom KN95 masks. But they are a tad longer horizontally and come up simply in an ear-loop choice.

The SupplyAid KN95 Protective Face Mask, sold in a pack of five, is non FDA-cleared. But nosotros noticed that a package we ordered from Amazon was manufactured by Suzhou Letian Protective Products Co., similar to a packet that had been filtration-tested by NIOSH, and that cess plant that the masks blocked out particles to an extent similar to N95s. (However, this is just one set of criteria that a respirator must pass to become a NIOSH-canonical N95, and the results are indicative just of the specific packets tested.) We ordered another set of SupplyAid masks and found them to be made by the same manufacturer, but packets nosotros ordered from Home Depot were made past another manufacturer, whose batch had not been NIOSH-tested. Nosotros've reached out multiple times to SnowJoe, SupplyAid's outdoor-equipment parent visitor, for clarification but haven't heard back. So we don't know for certain whether the version we bought on Amazon will continue to be manufactured past Suzhou Letian.

Armbrust Surgical Masks aren't FDA-authorized, but the CEO tells the states that the visitor has been undergoing the process for the past few months. (On its website, Armbrust shares a third-party lab written report suggesting that the mask meets ASTM Level 3 filtration standards.) Armbrust offers a fun range of color options typically not seen in masks, such every bit denim, orange, and dark-green. The mask feels a tad softer and thinner than virtually of the surgical-style masks we've tried. The nose-bridge wire feels sturdier, also, and the fasteners knot easily for a good fit. Frequently on sale, these masks are a proficient option if you lot can't get ahold of the DemeTech or Medline masks, or if you just want to add a burst of color to your mask wardrobe.

At around $12 for 75 masks, the FLTR General Use Face Mask, sold at Costco, is one of the to the lowest degree-expensive surgical-style masks we've seen. However, it isn't FDA-cleared. Like the company'south KN95-style masks, these pleated masks take been tested by a tertiary-party lab and institute to meet ASTM Level ane standards (blocking out at least 95% of 0.1-micron particles). The visitor redacted the manufacturer's proper name in the paperwork, again for "proprietary" reasons. (This mask is currently out of stock on Costco's site but may be bachelor in some locations when y'all purchase from Costco via Instacart. Nosotros also spotted boxes on Amazon, just those are from third-party sellers we haven't vetted.)

Unilever sells its Lifebuoy Face Mask at Target. A company spokesperson told us that tertiary-party lab testing has shown this mask meets ASTM Level 1 filtration standards (95%), simply the company doesn't share results. At well-nigh $xx for fifty masks (at this writing), the pricing isn't a notable bargain for a not-FDA-cleared box of masks.
