The Best N95 Masks in 2024 | NBC Select

There’s a wave of rising COVID cases across the country, so you may need to replenish your supply of face masks (and at-home COVID tests). The Centers for Disease Control and Prevention recommends wearing well-fitted respirators for the highest level of protection, including the N95 masks approved by the National Institute for Occupational Safety and Health.

I consulted medical experts to learn more about N95 masks, including the differences between KN95 masks and other disposable face coverings. I also compiled highly rated NIOSH-approved N95s that are available online. (Note that most people use “mask” and “respirator” interchangeably, but when the CDC and medical professionals say “respirator,” they specifically mean fitted face coverings with certified filtration, like N95s, KN95s and KF94s).

While shopping for N95 masks, experts recommend keeping the following in mind:

While there is a wide range of N95s that meet NIOSH’s requirements, surgical-grade masks should only be used by medical professionals, according to the CDC. Excluding them, I compiled the best NIOSH-approved N95 masks, which are expert-recommended and available to shop online. Note that some N95s come packaged together, while others are individually wrapped.

3M’s Aura foldable N95 Respirator has a three-panel design with two head straps and an adjustable nose bridge. The face covering is made to be low profile around the nose and eye area to accommodate glasses. The respirators come individually packaged.

Honeywell’s N95s fold flat when they’re not in use. They have head straps and an adjustable nose clip with a foam cushion that the brand says helps create a tight seal against the face. Masks come in a pack of 20.

DemeTECH’s N95 has a foldable design, meaning it folds flat when it’s not in use. The respirators are available in a pack of 20. They’re designed with five layers of material, an adjustable nose bridge and two head straps.

You can purchase Shawmut N95 respirators in a case of 10, 20 and 240. The masks are built with a piece of foam that lines the inside of the adjustable nose piece, which the brand says helps reduce eyeglass fogging. The N95 respirators have two elastic head straps and come in small and medium/large sizes.

BNX N95 masks fold flat when they’re not in use and have two latex-free head straps. They come with an adjustable metal nose bridge and are available in a pack of 20.

The pouch design of Kimberly-Clark Kimtech N95s creates a large breathing chamber, making it easier to talk while wearing the respirators, according to the brand. They’re built with two head straps and an adjustable nose bridge. The N95s come in a pack of 50.

Aidway’s N95 mask offers five layers of protection and has a flat-fold design. It’s built with two elastic head straps as well as an adjustable nose piece. You purchase the masks in packs of 10, 20, 50, 100, 500 or 1,000.

WellBefore’s N95 respirator offers four layers of protection and is available in a flat-fold design. It comes in white or black and is built with adjustable head straps and an adjustable nose piece. The N95s are individually wrapped and come in a 10-pack.

Breath Healthy’s flat-fold N95 mask comes with two wide elastic head straps and an adjustable nose piece. They come in a pack of 20 and are available in black and white.

Buying N95s is simpler than buying international respirators like KN95s or KF94s because they're regulated in the U.S. by NIOSH, says Dr. David Rempel, a professor in the Department of Medicine at the University of California, San Francisco.

When NIOSH gives an N95 its stamp of approval, it means “the respirator has met very specific requirements for testing. It is a quality assurance indicator that the respirator will perform as expected,” says Dr. Stella Hines, an associate professor in the Division of Pulmonary and Critical Care Medicine at the University of Maryland School of Medicine.

Medical experts told us that all N95s — whether they come in cup, flat fold or duckbill shapes — should have the following features:

You should not buy N95s that have exhaust ports, which holds true for all face masks, says Rempel. The CDC also states that “special N95 respirators labeled as ‘surgical’ or ‘medical’ should be prioritized for healthcare workers.”

Regardless of the type of mask you wear, it won’t protect you or the people around you unless you wear it correctly. The CDC recommends making sure your mask completely covers your mouth and nose and fits tightly against your face to prevent gaps around the sides of the mask, nose and chin.

“N95 respirators will provide the regulated, expected level of protection to the wearer only if there is a good seal to the face,” says Hines. “You want a good seal so that all of the air that is breathed in is pulled in through the mask body. That is where all the filtration of particles and microbial contaminants occurs.”

You can do an at-home leak test with an N95 by putting it on and breathing out, says Rempel. If you can feel the air under your chin or around your eyes, it’s not tight enough. And if your glasses are fogging up while wearing an N95, there’s leakage and it’s not tight enough, says Hines.

All masks and models fit differently, and features like adjustable ear loops and an adjustable nose bridge help you improve the fit of your mask, as do mask fitters or braces, according to the CDC. Using a fitter or brace is especially a good idea for people with facial hair, which can make it difficult to achieve a tight fit.

To recommend when Americans should wear face masks, the CDC determines an area’s Covid-19 Community Level risk on a scale of low, medium or high. To do so, it analyzes how many Covid-related hospital beds are in use, hospital admissions and the total number of new Covid cases in that area. Each Covid-19 Community Level corresponds to a masking recommendation — suggested precautions increase alongside the level. To determine your area’s Covid-19 Community Level, use the CDC’s Covid-19 county check.

No, you should not double-mask while wearing a N95 or KN95 mask, according to the CDC. You also should not wear respirators with exhalation valves or vents — this guidance applies to all masks.

In settings where workers are required to wear a N95, like some construction zones and healthcare settings, they must complete an official fit test , says Hines. The public, however, does not need to do a formal fit test before buying and wearing a N95. Regardless, you should still check to see if your respirator fits properly before wearing it in public, she says.

Technically, N95s are disposable, single-use face coverings. But if you remove and store a N95 properly, you can reuse it multiple times — simply put, that entails taking the mask off by its head straps and storing it in a paper or mesh fabric bag between uses, according to the CDC.

N95 manufacturers often provide instructions for the suggested length of use for their masks on the box or online. But in general, you should throw out your N95 if it gets damaged — crumpled up in your bag, for example — or if you can no longer achieve a tight seal to the face. You should also replace your N95 if it gets wet, dirty or contaminated.

N95 respirators are not intended for use by children and have not been broadly tested on them, according to the CDC. However, some brands offer N95s in small and large sizes, and smaller N95s may fit some children’s faces. Select brands make kids KN95s, too. When it comes to kids’ face coverings, it’s crucial to choose a well-fitting and comfortable option to reduce the chance of children removing it often or wearing it incorrectly, according to the CDC.

Experts have repeatedly stressed that masks help reduce the risk of COVID viral transmission. CDC studies have found that, between two properly masked or double-masked people, the risk of one giving the other a virus was cut by over 95%. Masking up also protects other people, as demonstrated in numerous studies like these gathered by the CDC.

Yes, N95 masks are eligible for reimbursement with a flexible spending account (FSA), health savings account (HSA) or health reimbursement arrangement (HRA). They are not eligible with a dependent care flexible spending account (DCFSA) or a limited-purpose flexible spending account (LPFSA).
