I’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.
