neither of these are ‘gases,’ really, you’re experiencing them in aerosol form
okay, there’s four types of filters
- 40mm NATO. most modern masks use this. this is the one you want, cause you can get newly made filters
- Soviet GOST. this can be made to fit NATO filters with some tape but it’s a pain. avoid
- cheek filters. you can tell these ones because the mask doesn’t have a visible canister hanging off it but big hamster cheeks. big avoid, they’re always gonna be expired and they suck

“I GOT THIS MASK OFF EBAY AND IT CAME COVERED IN WHITE DUST, WHAT DO”

okay great but a cop’s gonna rip it off your face and then you’ll be out five hundred dollars. also everyone else will assume you’re a cop
