Does this mask stop PM 2.5? I'm moving to China and this seems like a good option for having a non-disposable mask that is more breathable than the standard 3M type disposable masks. But if it isn't effective at filtering PM2.5, I think I'll stick with...

I am no scientists but this mask did the job for me. I felt much better cycling in the city. It is supposed to filter all kinds of particles, and the mask filter gets dark. So it works. Just one thing, because of the velo strap to close the mask you don't want any kind of wool cloth and scarfs. I ruined 2.

Page says: - Note: Washing filter material may reduce the filter efficacyI believe this is true, though of course they want you to buy their replacement filters.To save money, I'm thinking about buying these and cutting out own replacement filters from HEPA filter fabric:http://www.airfilterusa.com/commercial-industrial/air-filter-media/poly-dry-1-4-3-8-inch-dry-media

Yes they are HEPA filters. However, I've had allergic reactions using the 3M mask with these filters, and I don't think I would if the mask were truly removing 99.97% of the allergen. Some allergens leak through, somehow. These filters are the best I know of to filter out allergens, but I've had many allergic reactions to animal dander right through the filter. And to some kinds of mold. Either the filter itself isn't very good at filtering out some allergens, or other parts of the mask leak somewhat.

You can buy different filters that fit the mask. I have used the 3M 2091 in a dusty woodworking environment and have been very pleased with the results. Here is a blurb from the product sheet for the 2091 filter: "* OSHA substance specific particle exposures: - Lead -Asbestos -Cadmium -Arsenic - 4,4' Methylenedianiline (MDA)". Another filter is the 2097, which provides relief from particulates and organic vapors. Just do a Google search on 3M 2091 or 3M 2097, but it looks like you should be protected. I love my mask. Good luck.

Assuming that your fumes are organic vapors from diesel or gasoline--this should work just fine. This is also protect from any allergens from the lawn/grass cuttings. P100 filters protect from gas & vapors as well as from particulates, mold, bacteria. Great filter. Fits on both half mask and full face mask.

The mask can be used for gas filtration however what is also important isthetype of cartridge. If you are goin to use gas please use the 3m cartridge multi gas part no. 60926. It is recommended for most types of gases. Also please refer to 3m website for further information. Hope this is helpful. My husband uses it for staining wooden furniture and the smell does not affect him.

Don't know. I use to filter diesel exhaust from vehicles. It has worked for this purpose well. Unsure how long the thin carbon filter would last during smoke saturation. On other hand, this mask is compact and allows user to fit to face quickly and exit a pollluted area to a clear area. I would recommend as an emergency and short duration mask, to exit area to safety or to fetch a professional mask. After testing, you may find it works as well as professional fireman's mask.I have used this mask extensively around diesel exhaust without a problem.My alternative mask was to use a professional paint sprayer mask, with which I had decades of use in my business.

This mask would be 'overkill'. It filters down to organic/petroleum vapor level (2.5 microns). A simple dust mask will be just as effective for your usage.

No, these are specific particulate filters for dust, and organic compounds. I would go to the 3M site and search for Mig welding respirators. That would definitely point you in the right direction. That way, you will know you will be safe. Good luck!

I can only respond as to the filter I received from Boair. The problem I experienced was the filter's inability to capture particles that an inexpensive filter purchased from a big box store was successfully blocking. I consider the filter provided me by Boair, a complete waste of money.

Elizabeth-This is a particulate filter, it will NOT remove ANY odor as there is no activated charcoal to remove odors. I would recommend a nuisance filter mask as a minimum. A half face respirator would be a better choice. Also, if the odors are that strong, I would look at the MSDS for the fragrances and look into better ventilation as part of the solution. The fragrance manufacturer should be able to recommend what type of respirator cartrige would be best.

I am not sure, sorry. This is the only mask I have ever purchased and I am happy with it.

Mold spores are too large to make it through the mask filters. If mold is all you are trying to protect yourself from, you can use the disposable "N95" masks.

I have no problems breathing with it. I tried the Sly Profit before this but I had a hard time breathing on that one. You can definitely hear yourself though with this mask compared to the profit. I hope this helps.

We bought the masks specifically for travel in China (Beijing) where the smog is awful, and i wore one mask for the 3 days we were there with no problems. I would probably say 5 days itf used for smog but from dust and dirt that depends on the job and the length of time and i've not used for this work as yet.

3m P100 / HEPA filters for the Safe-Air or 7000 series respirators fit in there nicely. The Power Mask puts a gasket in the mask, and the 3M 7255 has a gasket on the filter. The result is a very good seal, though you'll have to crank it down a bit - the 3M filters are ever so slightly smaller than the Safe Air filters. I've switched to this combination for cutting fiber cement, and I can no longer taste the dust halfway through a cut. Airflow may be slightly reduced compared to a Safe Air OEM filter, but still adequate if you're not doing gymnastics. I don't care if the original ones suck; I'll simply use them to make mowing the grass-optional portions of the yard less miserable. 3m P100 / HEPA filters for the Safe-Air or 7000 series respirators fit in there nicely.

That will depend on the concentration of polutants in the air of the area where you are using them. For me, they last until I start feeling too much smell (in the air that I'm breathing) inside the mask or when I start caughing too much. It means the filters are already getting too dirty. Another thing you can do is check the colour of the filter in the inner side, the small hole where it attaches to the mask. If it starts getting dark, I think you might need to change them.
