Would it be safe to use an MS-4 to filter particulates? - Can it filter asbestos? Is the chromium of a similar composition to the filters that the US tested? Coming up with the result that it isn't dangerous.

I would also like to confirm that it has a GOST thread, also wondering about how exactly this compares to an MS-3.

I have an MC-1 gas mask and would like to wear it with an original filter, not a newer one. They look cooler too me.

Hello everyone. Recently I bought a 75M gasmask kit later version, the filter is brand new, not leaking and it's made on 1989 may 31. The filter is asbestos free or I should buy a newer 40mm filter for it ?

Hello, I have a bough a PmK2 gas mask and I need to know if the filter that came with it is safe take a look at the picture

I plan on purchasing a Swedish Folkgasmask Typ 32 (And i will wear it for cosplay uses) but i want to clean it before wearing for my safety, but from what i've researched you need to replace the filters. is there a way to clense gas mask filters ? if not is there a way i can put on a different filter (not an affective filter- just for looks) for that model ?

Does anyone know the visual difference between an M10a1 and an M10a2 filter canister?

So yeah, not technically a filter I guess, but one from an N95 face mask? Would that cause inflation? Seeing as I would be using P3 main filters, nothing large should get past because the P3 filters have higher protection levels than an n95, so theoretically nothing too big for the N95 should go through the P3? Maybe I'm wrong, but it seems like a good idea if it doesn't cause inflation.

So im wanting to get a GM38 gas mask, and i was wondering what filters would be safe to use? I am planning on wearing the gas mask and wanting to be able to use the filter

I got a Romanian M74 a few days back and it came with a CF-4 filter. I have heard conflicting things about the presence of asbestos or any other hazardous chemicals, and there's no page that actually lists information about their composition. A few years ago, someone here asked if they were safe to mixed-to-negative responses, so I figured it wouldn't hurt to ask again. The black print on the side reads:

CF-4

LOT 82-11-79

380 22

I'm not sure exactly what it could mean, but I assume the manufacture date may have something to do with the numbers? I imagine the filter would most definitely be expired by now, but I'm not so worried about it being expired as I am about it being toxic.

EDIT: It's also worth noting, probably, that I did shake it and there was no noise. Also, I did the white paper test and nothing fell out.

I bought one, opened it, looked at it. Shook it three times then put it in the trash. Am I in trouble?

I have a Soviet mm-1 mask, I cleaned it well, I used it afterwards (I used it with a modern filter), and within a few days of using it I suffered from a constant sore throat, have I inhaled asbestos?, or does anyone know if the mask contains asbestos?
