Chemical Protection[]

Because of this, he cannot be held liable for any damages incurred from improper use of this filter. It is highly recommended that any individual seeking to use this filter get proper professional training before working with hazardous chemicals requiring such protection.)
The filter canister appears to protect against the following chemicals as per the seller's description on ebay:
"Gas filter A1 is designed to clean the polluted air from organic vapors with a boiling point above 65 ° C (eg , benzene, xylene , toluene, gasoline, kerosene, organic halogen compounds , nitro compounds of benzene and its homologues , ethers, alcohols , ketones , aniline, tetraethyl , phosphorus and organochlorine pesticides ) . The filter housing is made of special plastic and fused absorbing layer ( the charge ) of the sorbent. Gas filter A1 is used in a filter mask (with a full face mask)."
From this description, it can be argued that this filter protects specially against industrial organic vapors and does not specialize in chemical weapons, biological or radiological threats.
Based on markings on the filter, it has a storage life of 7 years from date of manufacture with the pictured example having been made in 2012. The sticker on the front shows the dates 2001, 2012 and 2004 (unsure what the year of manufacture is as it is in Russian).
Physical Description[]

Unlike older Russian filters which can be hard to tell if used or spent, the PPM filters have a seal tape that requires removal prior to use.
Even the top screw cap has a seal tape.
The rest of the markings are all in Russian.
