This respirator is fairly comfy, always seals well, and comes at a reasonable price. I've used it while bleaching mold, spray-painting ceilings, caulking with nasty outdoor-only rated caulk, cleaning with mineral spirits, and it's quite amazing to take it off and realize how much I stunk up the room but didn't know it. Definitely a must have for any DIY-er or professional. I've had one for a few years now and now think it's one of those safety items everyone should have.
