I think it will filter pm of 2.5. I mow the lawn with mask to prevent my allergies from acting up! And since I have used it to my allergies are fine. And it is very breathable.

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.

the sizes are off on this mask - its not comfortable and I rather not use it. I have used it in a few dust storms on cross-country races. the filtration is pretty good for that. I didn't taste or feel the sand in my nose or mouth.

The filter is specifically designed ONLY for the filters that come with the helmet. HEPA is not an option unless you alter the unit. No this not HEPA, in fact I had to try and improve the helmet, if you need that level of protection get a non electric form fitting filter mask MSA or other from wood craft look at the cat. These helmets give you the minimum requirements go figure out the price as to why they charge so much for something that is inferior to other non powered ones.

I have sensitivities to chemical odors and they do not work for me. These are mostly for filtering submicron particles such as dust and pollen. If you want to filter chemical odors you need something with charcoal in it. I use "Air-Aid" Emergency masks. They are lightweight and have charcoal embedded in the fibers. They are use by police and fire departments and have been tested against chemical and biological weapons. Since I am very chemically sensitive I layer 2 masks on top of each other, but they work for me. Hope this helps.

I have used the regular ones in the past and got the smoke stop ones last time to see if it was better and I will be switching back to the regulars because the smoke stop ones restrict airflow to much and needs to be run on high power to be effective. I will keep them so if I have a rare situation of smokey air etc I can put them back in. Hope that helps

Here is an answer directly from 3M:From 3mFor light exposure to cigarette smoke, 3M has suggested a disposable N95 or P95 respirator with nuisance level organic vapor relief. This would provide some temporary relief from cigarette smoke, without being overly obtrusive. For better protection from the particulates, a P100 could also be used on a half-mask.

Hesitate to give an answer, too many variables. It would be the same as any other filter mask. The replacement filters cost less than buying HD or Lowe's masks. Its a cheap mask but it works. I use it in attic's and for drywall dust.

Hi. I went through the same thing and checked the 3M site. For the mask you may buy different kinds of filters. The one that is for dust, like for a woodworker, has a filter inside that looks like a cars air filter. The one for chemicals has a different filter inside and you may use these pre-filters. Put one of each cartridge facing up. They fit into the ridge around the filter and a cover keeps them in place. Hopefully I've been reasonably clear otherwise feel free to ping me again.

Check any review or description of E-PM2 online for your answer. They are pros.

Ok, I will answer this question based on experience. It does block odors. I wear this mask in a location that burns their trash in a pit. The fire is some times accelerated with diesel fuel. To say it smells toxic is a huge understatement. This mask will block the smell. It is actually amazing. I wear the mask at the location I work and it is amazing what I can't smell. Anyways, this mask will block odors that are particulate odors such as an open burn pit.

It depends on what you're doing - I got this filter because it seems to be pretty all-encompassing: http://www.amazon.com/3M-Low-Maintenance-Cartridge-Purifying-Respirator/dp/B00AEFCP0E/ref=sr_1_1?s=industrial&ie=UTF8&qid=1392297594&sr=1-1&keywords=6006+filter It's been effecticve for fiberglass insulation, sanding plastics and composites, spray painting, etc.

You get plenty of air thru the mask. I never felt suffocated even with the charcoal filters. I have trouble breathing even without the mask, yet I never felt suffocated or even slightly air deprived.

According to the cdc, masks rated n95 or better will stop the virus when it is in liquid drops,, ect. If the virus mutates to an airborn varity, then none of these types of filters would work, as the virus itself is two small. The mask is rated p100, which is even better rated then the cdc recommends. It also resists oil based droplets. And is oil rated, that's what the p in p100 stands for

sorry, but I don't know if it will fit another respirator. I do know there are different cartridges/filters based on what you want to filter (particulates/dust vs. fumes/vapors. I think this cartridge is the actual filter, the small cotton pads that are also available are a pre-filter. hope it helps. You might find the right answeres on the 3m website.

The mask is designed for particulate matter -- dust and pollen, but would probably not help much with air pollution or airborne viruses. I am not certain of what you mean by "living in China", but if you mean polluted or contaminated air, then no these would not help.

I only used it for biking around my city. I wouldn't run with it. I get called a terrorist from passerbyers. I use another mask from respro. This one is made in Poland if I recall. I could still smell some odors, which you shouldn't, if it is working properly. Vogmask is another good alternative. They both are good at blocking odors. But you need to change the inner filters and wash them. i soak it in boiling water after 5-10 uses. Hope this helps.

It is rated for N95 which supposedly filters out 95% of particles. They don't state pm, Not for toxic or harmful substances such as lead, asbestos, and oil containing vapors, hope this helps.

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
