i wear a 3m 8210 respirator n95 mask. have used it when i was a painter and also working on the farm in all the dust. also have sometimes put a damp kleenex inside it for further relief.
as an asthmatic taking the bus a lot i'm around 2nd hand smoke so much that my asthma is worsening. mask recommendation. i want to know if there is a mask i can wear while waiting for the bus when i can't get away from smokers. i went online searching and couldn't find anything. all the websites i visited said it was impossible to really filter the cigarette smoke completely. so is there a mask that will do a fairly good job? maybe i can wear two of those masks at the same time to better help myself. thank you.
