Reply to comment by Cult_ureS in Will a bag of activated charcoal actually passively purify the air in a room? by gtmattz

I was going to comment that HEPA is for particulate filtration but won't be helpful for chemical vapors. A small amount might adsorb, but a filter designed for vapors (usually with activated charcoal in it) will be much safer.
