This standard rates masks based on filtration, breathability, and an optional leakage ratio. The CDC has a list of masks here, and it tells which masks pass enough of these criteria to qualify for either of the Workplace Performance labels (as of writing, there are only three that earned the label), but this is all based on data reported by suppliers and manufacturers. If you can’t find N95 masks but don’t work in a high-risk setting, these are also decent masks to pick up.
Also, note that ASTM refers to the agency that classifies standards, but this workplace standard is not the only ASTM standard that governs masks. This standard is technically ASTM F3502-21, which only has the two Workplace Performance levels mentioned above. You may also see other masks that use labels like “ASTM Level 3,” which refer to different ASTM standards for medical masks. For our purposes, all of this means that if you’re looking for low-risk masks for the office, look for the Workplace Performance labels.
N95 Respirator Face Masks
The CDC has a giant list of approved N95 masks. Unfortunately, the supply of many brands is constantly fluctuating (even in 2024), so you may need to check back regularly to see which are in stock. Many stores also have regional stock based on in-store supply, so be sure to check your local zip code at different sites where applicable.
If you need a large number of N95s on the cheap, this pack from Kimberly-Clark is one of your best bets. While these are NIOSH-approved N95 respirators, they’re not intended for medical use. If that’s not an issue for you, then the horizontal-fold pouch and bendable nosepiece should provide a solid seal on your face, while still costing less than a dollar per mask.
This fold-style mask uses two over-the-head straps to keep the mask snug on your face, while still allowing a fair amount of breathing room in front of your mouth and nose. These are among the pricier masks on our list, but members of our team have used these and found them comfortable and sturdy.
3M’s N95 respirators are individually wrapped and have two horizontal folds that create a decent-sized cup in front of your nose and mouth. The masks come with two straps that go over your head and neck to keep a tight seal. This is one of the smaller packs on our list, but you may have an easier time finding it in stock at some stores.
The DF300 N95 from Honeywell is a more affordable option on this list. With this mask, you’ll get multilayer absorption (including a humidity- and moisture-resistant filter), a soft inner lining, and latex-free head straps. The nose clip is also adjustable and hidden underneath the mask. It comes complete with a soft foam nose cushion as well, which should make it more comfortable to wear for longer periods of time.
KF94 Masks
Vida’s KF94 mask is both protective and stylish. It’s FDA-listed, CE-certified (and manufactured in South Korea), and offers a 94 percent filtration efficiency. The four-layer mask comes in adorable colors including Blush, Seafoam, and Glacier Blue. It’s also available in a variety of pack sizes, from 10 to 10,000.
The BOTN KF94 masks only come in large and extra-large for adults, so those with smaller faces should look into the youth size, which also comes in a variety of color options including beige, dark gray, pink, and yellow. The mask has ear loops and a nosepiece that are both adjustable, so it should help ensure a tight fit if you go for the bigger size. I (Brenda) prefer these when wearing makeup, because the nosepiece stays put and doesn’t ruin my foundation as much as other masks do.
This one dips in and out of stock. LG’s Airwasher mask is a standard KF94 with a three-dimensional design, four-ply fabric, an adjustable nose clip, and rounded ear loops. If you want a slightly more elevated option, it also comes in a Black Style design that’ll likely pair well with fancier outfits for more formal occasions.
KN95 Face Masks
Evolvetogether’s masks are trendy among celebrities because they’re both protective and stylish. The Rio De Janeiro is made of six-ply fabric (complete with activated charcoal to reduce odors), double filtration, and a water-resistant exterior. Each mask also has an adjustable nose bridge and gentle ear loops, making it ideal to wear for long periods of time. Of all the KN95s we’ve tested, this is our favorite one for smaller faces. While pricey, these masks are not only lightweight and comfortable but super durable as well.
This mask from Halidodo comes in several color sets—one of the options includes eye-catching orange—and is similarly affordable.
We’ve tested this mask and found that, while comfortable and super durable, the size is best for those with smaller faces.
The white Powecom masks come with a multi-filtration system and an adjustable metal nosepiece. You can also choose between the standard KN95 ear loops or the N95 headband style, depending on what you find more comfortable.
Masks for Kids
Once kids are over the age of 2, you can consider putting a face mask on them. We recommend anything they’ll actually wear. We have a suggestion below, and our Best Face Masks for Kids guide has more.
Kids’ masks are a bit more difficult since health agencies don’t regulate them in quite the same way, but this pack of KN95s is one of our favorites. It’s reusable and can be worn by children 3 to 12 years old. It comes in blue, white, or pink. It has been independently tested by several international product-testing and quality-assurance companies, and it is the mask that WIRED editor Adrienne So’s kids used for school.
Our mask reviewer, Adrienne So, had her kids test these. She said they fit them well, and well-fitting masks for kids are hard to find. They come in three sizes, for different ages, and should provide protection similar to a KN95—more protection than a standard surgical-style mask. There’s frequently a coupon on the page you can clip to knock a few dollars off.
If You Can’t Find a Mask, Try Project N95
Project N95 isn’t a specific mask but rather a nonprofit devoted to connecting personal protective equipment (PPE) supplies with the people and health care organizations that need them. During the height of the pandemic, it offered the ability to browse the organization’s marketplace to find more masks and respirators as well as testing kits and other protective gear.
Now that the national and public health emergency has ended, Project 95 still offers access to previously vetted authentic and highly protective masks. But now each mask links to a third-party website (that isn’t controlled or operated by the nonprofit) to purchase them. The organization says these links are up to date as of January 31, 2024.
