You must be in Shanghai or another city in China too. My husband's employer's HR department recommended the 3M N95 masks. I am using them and I truly hope that they are effective since the AQI here has been around 500 yesterday. I think PM2.5 hovered at about 300. Wish I could give you a definitive answer. I do notice a difference between when I am wearing a mask and when I forget to put in on.

Can't answer that Matthew. I bought a bunch of these & sent them to US military staff overseas because of polluted air to help them sleep better.I suggest checking at the 3M website for specific info and/or checking with their customer service folks. Good luck. Doug

These are particulate filters...they would screen out some of the fine particles, but none of the toxic gases. Plus, you will find a social cost associated with wearing (the mask that mounts) these filters to work. I wear my mask with these filters for when I mow/mulch the yard...they do a good job of keeping yard dust out of my lungs.

I doubt it. It is just a thin carbon filter. Plus the mask doesn't conform tightly. I have a gap under my chin. It is ok for dust, but I wouldn't trust it for anything else. For health reasons alone, I'd go with a more serious 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.

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.

NO! Repeat NO! Use these: 3M 6001 Organic Vapor Cartridge, 1-PairThe 2097's are GREAT for grinder / sander dust though, and GR8 value!Lets take that one step further. A couple years ago I used a NEW 6001 cartridge, nitrile gloves, tyvek suit from head to toe and sprayed ppg amerlock II for a small project - less than a dozen sq ft. Had shortness of breath from the isocyanacrylates (?) for FOUR days after. Those need a scuba suit with supplied air or an air wash spray booth industrial system for that.

Yes, that should work fine. Verify the filter states it's acceptable for dusty applications. Also while using the mask if it starts getting harder to breath change the filters. Have fun!

Question back is what pollution? Particulate, pollen, polluted fog, industrial gasses? It is NIOSH approved for dust. Not asbestos or heavy metals or chemical based pollution. There are other N100 masks and 3M half face masks that have the opportunity to use a variety of disposable filters for a variety of problems. Remember your eyes are entryways for a lot of really nasty pollutants.

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.

Whether it works at all is still open to question. I've used in on about 12 international and domestic flights and I haven't got sick like I used to. I've started to use it on the subways in China where I work. Even if it is effective at eliminating particles, I suspect it would not be effective against PM2.5 pollution. You need special masks for that.

With a properly fitted / sized mask, these filters should do the job perfectly! Using a pair adaptors with the dust filters to stack over these filters' inlets should prolong their use life by capturing most of the actual paint mist droplets before they ever get to this quality vapor/fume stopper. Most claim that with the #6001 in use, you don't smell anything...not a trace!

It mostly depends on the width of your face as to the size, at least that is what I found. I have what most would consider a pretty average - male - face in medium worked fine for me. Make sure you get the right filter for vapors and should be great. I would never go back to a 1/2 mask as the full is so much more comfortable and protects the eyes. Happy spraying. PS, I noticed that you said mold. If there is mold there now make you have a mold filter and please wear a full suit for own good.

Look for a mask respirator. The type that blocks dust should do the trick.safety Glasses for eye protect.

it depends on which type of filter you get for the mask. There are different grades of filters that are intended for different purposes, depending on what type of work you are doing. There are filters you can buy that will filter out gases and lead particulate.

Probably ALL filtering face masks have some kind of breathing resistance. It is a covering, after all. That said, I have found the microfiber Vogmask to be comfortable to wear without too much resistance. I used it cleaning up a very dusty room, had it on for over an hour, and didn't encounter any problems.---Charles Foster Dudley
