I know before the 70's, filters we're bad.
Are there any 40mm filter that was manufactured earlier that date? (Not the coffee can type)
-I am pertaining to the filters that comes with the gas masks that are being sold here.

I dissected the filter I have with me (40mm filter) and all I found was paper, activated carbon and mesh.
I burned the paper and mesh, mesh burned BUT NOT THE PAPER. I read and have been told that Asbestos DOES NOT BURN.

Turns out I'm not poisoned, so all the other filters dating back to 70 until today won't have any Asbestos.

...I'm not sure about the TF 1 set issue though! (GP 5 replica, they also copy other models) They issue a coffee can filter, but smaller than the soviet issued ones

Actually, I inhaled the smoke that was burning from the Aerosol filter, no breathing problems what so ever...
But the Aerosol filter did smell really bad, worse than burnt hair. lol

BTW! The paper in the filter is Aerosol filter! Very Happy

I guess I was just paranoid? Hehehehehe...

Will do more tests my self (Hopefully it don't kill me)! xD

Save yourself from the pain: http://www.gasmaskforum.com/is-the-russ ... e-t13.html

They contain no asbestos. It is tightly woven, chemically treated cotton paper, with activated carbon to absorb and filter the air.

Aye.

But breathing through it ain't good. A friend of mine did so once, and he's been kind of short of breath ever since.
Should've listened to me...

Not sure what kind of problem he had, I've been using mine for awhile off and on, no problems here. Unless he was using a British or German filter.

Thought the same. I've been filtering gases (might come out wrongly) with my soviet filters without any problems.

Or... He might have gained proper weight recently, reducing his conditioning, and just blamed it on this. lol

The filters dont contain anything harmful, the asbestos scare pertains to ww2 era and prior gasmasks. These did contain asbestos fibres as at the time they were made the harmful effects of asbestos werent recognised. The warnings were issued because during the post-911 anthrax and other CBRN-nasties scare people were rushing out and buying any gasmasks they could find (and unscrupulous vendors responded by jacking up their prices) and wearing them, and a lot of people didnt realise that such masks would not only be useless because the absorbent in the filter would be exhausted, but the mask would be actually harmful to their health. Couple that with the fact that people probably wouldnt have access to CBRN detection kit, decontamination equipment, fresh suits and filters, then it makes you think how little some people actually know about these things!!!

What about the DP-1 connector filters? Are they safe to use?

You mean the gas mask hoses?

They are fine, it is a thicker material like what is used on Russian chemical suits on the inside and just some kind of synthetic fabric on the outside painted and treated to prevent chemical agents from adhering to the surface. The only thing you might do before use is run water through it to get the chalk dust out, it preserves latex and other rubber materials.
