Who knows. If it's better than nothing.
Wouldn't hurt to get one of these. ALso good for fire season smoke, not sure if that's an issue in your area. Much better than the paper masks. You can't smell cigarette smoke or acetone wearing one of these.
Rated P100, better than N95. Most are from China now, the ebay ads sell out quick. Search for 3M 6500 half mask, 6200 seems to be the same thing, 2091 or 2097 filters, the latter slightly better. I use medium size, seems to work for most people.

Welding supply stores might have them, doesn't hurt to check.
