I use the 3M Charcoal respirator every day , but make sure you get one that fits snug to your face and seals ( S, M & L sizes ) , can NOT be used with facial hair ! Mustache is ok but not goat -T or beard .

I also use the 3M full face Charcoal mask too , uses disposable charcoal filters that can be changed when needed ( and you can buy to replace them ) , and I buy a package of tear offs to keep the lens clean of overspray . I like it better as these high solid clears bother my eyes , and Isocyanates ( catalyst or hardners ) go towards moisture
With these masks , make sure you seal them in a big zip lock baggy to help make them go farther as once they are opened they will filter air constantly and therefore reducing protection & made useless .

Any one of these will work for a person that doesnt spray all the time & everyday . No need to purchase a high dollar fresh air unit for a few times spraying . I have been breathing this crap for 30 years and havent died yet , but the lungs dont have the capacity they once had and I dont have 3 arms or 15 toes , and not bald ........ ha ha ha
