Input:
Does a very good job.  I've used it with spray paint, ammonia, bleach, insulation, smoke/dry chemical fire extinguisher, and generally uncleanly environments.  Although I have a short beard, I am pleased with the coverage and seal that it can make.  Because of my beard, I knew a half mask would not be ideal and/or perfect, but this mask does the job sufficiently for my tasks.  I haven't had to replace to cartridges yet.
