WC Safety editorial note — 3M 9211+ N95 Disposable Respirator with Cool Flow Valve
NIOSH-certified 3M disposable respirator — full specs, compatibility, FAQ, and ordering below. Read our independent review → or see the Disposable Respirator Complete Guide.
The 3M 9211+ N95 Disposable Respirator with Co is a NIOSH-approved N95 disposable respirator that filters at least 95% of non-oil airborne particles. It is the industry-standard choice for general construction dust, sanding, drywall, wildfire smoke, and nuisance particulate. As a cup with an exhalation valve respirator, it is best where breathing heat is a concern. Sold multiple per pack.
Step changes by hazard: for non-oil dust an N95 covers most work, R95 adds oil resistance, and P100 gives oil-proof 99.97% filtration. For gases or vapors, no filtering facepiece will do — use a half mask respirator with cartridges.

Reliable brand, good and secure protection, easy to breathe, long-lasting
During the pandemic, I shopped around for a lot of masks. I really want to stick to 3M given their reputation in this market. Their masks provide good protection with published reliability data. Unfortunately, these weren't available during the worst of the pandemic, but I still like to use these today in crowded public areas or while traveling. The filter makes it a lot easier to breathe, so I can keep the mask on for hours at a time (I've traveled for 20 hours, only removing it 3-4 times for meals). The cord is also like braided cloth, so it's more sturdy than the rubber band material, which means it lasts longer. The prices fluctuate a lot for these masks, but given the longevity, I think $2.50-$3.00 per mask is reasonable.

Good quality mask with tricky fitting
Good quality mask but definitely recommend buying a single mask when possible to check fitting, as they were quite small for me. The straps are fairly soft, though do get painful on the upper ear with prolonged use as most masks do. Importantly the straps have not broken on any of my masks despite repeatedly taking them on & off and not being particularly ginger about it. The straple point on the mask where the straps attach can also scrape against the cheek, which can be uncomfortable, but with some adjustment this is fixed.

easy fit for anyone
The 3M Aura Particulate Respirator 9211+ is hands down one of the best N95 masks I’ve used. The individually wrapped design ensures each mask stays clean and ready for use, which is a huge plus for both convenience and hygiene. The three-panel design provides a secure, comfortable fit while allowing for easy breathing and speaking, making it great for long wear. The adjustable nose clip and soft inner lining add to the comfort and help achieve a proper seal. I also love that it folds flat, making it easy to carry and store. Whether for work, travel, or general protection, this pack of 10 respirators is a reliable, high-quality choice!

Very small and tight, valves may not work well
These masks and the straps are incredibly small and tight. It's weird. I have a child size head (wear child size hats), and most masks are a little big/loose on me. These are so tight it hurts--the top straps are painfully cutting into my ears (and both straps are so tight it feels like they're going to break when I put it on), and the mask is tight on my small face--squishing into my small nose. I do not understand this. These are supposedly "one size," and the box says "Standard Size" on it. I've tried a few of the masks, all have same issue.I also am not confident the valve is closing properly--I can breathe in (inhale) much easier than with any other N95 mask (including other valved 3M masks in a different model), which makes me wonder if air is getting in around the valve. So, I don't trust it to protect me. Very disappointed.[NOTE: I ordered these sold by amazon and was initially shipped a box that had been opened and returned (someone else's amazon receipt was INSIDE the 3M box, which had been taped up)!! Disturbing. Amazon said they couldn't replace the item (no idea why not), but did refund me for it so I could order again. But every time I went to reorder, the price would jump up ~$6-$10 over what I'd originally paid. I'd wait a while, see the price go down, and then it would jump before I could get the order placed. Annoying. After several days of this, I eventually gave up and got the masks elsewhere.]

Fit excellent but elastic straps can be an issue due to their relatively short length.
The mask itself fits well seals tightly but the only real issue is the length of the elastic straps being too short which make the mask uncomfortable after a short period of time. I didn’t see an option for a different size.Other than the item mentioned above everything else was great the breathing valve worked well reducing the heat associated with masks that don’t have this feature. I would definitely recommend as long as the size works for you.

The Only Mask I Use
These are the only masks I use. I'm immunocompromised so, when I'm in a situation where the risk of respiratory infection is high, I need a mask that will give me excellent protection. I've done a fit test with this mask and didn't smell or taste anything until the end of the test when I was told to loosen the mask and realized I had been breathing air that smelled and tasted horrible. When I'm in a situation where others are masking, I use the Aura without the valve, but when others are not masking (which is almost always the case these days), I find the Cool Flow Valve makes it a lot easier to breathe through the mask. I have sensitive skin and some masks give me a rash or are very irritating, but this mask doesn't bother me at all.

Elegant mask design, highly functional respirator, but too small with staples that can poke
Inexplicably small and tight-fitting, considering they are not marketed as being the "small" size within a range of sizes, these masks' elastic bands are either too short and/or not stretchable enough (notably the upper band). Also the staples that anchor the elastic bands are prone to poke the face.This all is too bad since the design of the mask per se is excellent, and the respirator is the best I ever used: in summer at least, I can wear these masks while wearing my glasses, without my glasses fogging at all. That is a first for me.

Easy breathing
If you need and or want an n95 mask, and you want to have the easiest breathing experience possible, I highly recommend this product. I have spent a lot of money on different masks, I've probably bought 30 different brands models and styles. In the n65 end of the world I have to say this is hands down the best mask I've had. The one way breathing Outlet makes it so much easier to breathe, and keeps your mask from getting filled with hot air and steaming up your glasses or just making you generally uncomfortable. The bands could be a little bit looser, but there are ways to adjust them and make them fit more easily. Overall I still give them a 10 out of 10 for being the easiest to breathe through. The only issue I had was shipping, it took forever.. but then again that is kind of understandable seeing how they are such great quality. I bought mine for my trip to Hawaii so that when I'm in my Tin Can for 20 hours I make sure that I don't get sick and waste half of my vacation. What will you use yours for?

Cooler than masks without vent
Best and safest Covid-19 masks available with vent. May not be permitted in certain health facilities due to exhaust vent however. Have used 3M model w/o vent for years safely. Vent model also has stronger head bands.
