A while back I purchased a 3M 6502 face mask for working with shellac, lacquer, etc. I got one of their techs online via chat and they recommended the 3M 60921 cartridges. So far I've been very pleased with it. Easy to get on and off, can't smell anything while wearing it and the quick release in the front lets you lift it up from your mouth to talk (or take a sip of coffee) and then quickly latch back. Light and simple. If you're in the market for a mask for fumes I would recommend it.
