I just wore a half face respirator with an activated carbon filter (3M 7503 + 6001 + something over that for particulates, probably 2297). Quality respirators seem like simple table stakes for doing a lot of things these days. It was an off label use of the organic vapor cartridge but it worked fine (it also worked fine for cleaning with ammonia in deep cabinets). I also probably plugged the O3 generator into an extension cord which I could unplug without going in the room, the mask was just to go in and open the windows some time afterwards. It seems like, as with anything, the important part is to know the technicals of what something does and create an overall plan.
- ok_computer 1y agoI’ve used respirators through prior lab work and be warned the ammonia grade and organic solvent grades are distinct filter packing.
- mindslight 1y agoSorry, that's what I meant to imply about off label use. I should have stated it explicitly. Household cleaning one would otherwise moderate their exposure "by smell", so I'm comfortable trusting my sense of smell through an activated charcoal filter even though it's not a listed use, is past expiration, etc. For things (eg painting with isocyanates), I follow the directions religiously.
