Self reply to all others: try doing something that actually tests the limits a bit for health reasons. you can tell in a welding/woodshop when N95s and P100s go bad, they get physically harder to breath through after about 6-8 hours. If they don't they're not sealed well enough. they do keep working longer (probably), but they get quite a bit worse.
- scarejunba 7y agoDoesn't really apply to the situation being discussed. You can absolutely wear it for two weeks during the fires. It will work just fine even well sealed. Not sufficient particulate matter in the air to be significant blocker.
