3M Particulate Respirator 8247, Pack of 20, R95, NIOSH APPROVED, Nuisance Level Organic Vapor Relief, Braided Comfort Strap, Carbon Filter Material, Disposable General Purpose for Dust

Great product, highly effective at removing most volatile gases and particles. I just wish they made a version with an exhaust valve.

I work around formaldehyde and this helps significantly. Great product! I recommend!

I purchased this mask in order to block fragrances, smoke and chemical fumes. This mask does not fully block any them but, it does cut down significantly reduce on how strongly I perceive them. (Note: To block any of these things fully requires filter cartridges with many more layers of carbon.) * I was able to breathe in a car when surrounded by people cloaked in 2nd hand smoke (when without the mask I was miserable). * It's gotten so one cannot go a retail shop without being ambushed by candles, perfumes, or other smelly products (e.g. specialty soaps). I was able to peruse gift shops at the airport without pain despite large displays with heavily scented items. * The mask helps when traveling. In some places it seems like they clean rooms or vehicles with undiluted bleach or some other similarly potent concoction. This masks makes it so I can occupy the space until the fumes wear off. Gripes: I have two issues with this mask -- it's itchy and the straps are too tight. After a few hours, it gets to where I have to remove the mask periodically to rub at my skin due to the itching. Separately, the mask can cause headaches because the straps are so tight and cannot be adjusted. Overall, I'm thrilled to have this mask available to me, but I wish it was more comfortable to wear.

If you’re looking for a mask that eliminates odor this is what you need. I’ve been using them for over 25 years in the painting business and they truly stop organic compounds and heavy duty smell smells. They’re a little pricey because they’re 3M, but they are well worth it. You can get multiple uses out of one.

I bought these since I figured I ought to have some 95+ disposables just in case. They’re just about the easiest to breathe in 95+ mask I’ve ever worn, and as an R mask (instead of the more conventional N masks) light oil aerosol protection is useful to me for hobby use in my workshop as well. I’ve been wearing one as my primary mask for several weeks now, and it’s hanging together surprisingly well for a 95 mask, much longer than I expected for a disposable. It’s also one of the best-fitting disposable masks I’ve ever tried, giving a great seal. Edited to add: It turns out that the filter material used in these versus an N95 is a more expensive material, and that's why it's so much easier to breathe in them.

good filters

I have a neighbor who installed an Outdoor Wood Boiler 150 feet from our home (currently "grandfatered" after the town decided to regulate). When the wind is from the NW, the acrid smoke, laden with fine, carcinogenic particles, envelopes our home and often finds its way inside as well. Our very lives are literally dictated by the direction of the wind. When we find it necessary to do chores or otherwise venture out on "smoke" days (~ 80% of the winter here in northern Wisconsin) we found that the 3M 8247 Particle Respirator provides the very best filtering of any of a dozen or so products we've tried. I was told that a rule of thumb is "if there is any smell ... there are particles". When using a properly fitted 3M 8247, there is no smell whatsoever. For information on OWB hazards, do a web search using "OWB Hazards" and "smoke particle hazards" as subjects.

Overpriced but no substitute for shop use. Fabric elastic bands last far longer than the generic XXX95 rubber bands made now.

Cumple muy bien su función evitando o disminuyendo los olores. Para una persona asmática como yo me resulta muy útil. Llegó antes de lo esperado.

los uso para cuando tengo que ponerle gasolina a la herramienta de jardin
