The GP-5 filter canister is a Russian-made 40mm (GOST thread) combination filter designed to protect against NBC threats. Introduced during the 1970s, the filter and the GP-5 Gas Mask that came with it is the most widely-used gas mask and filter model in the world. It is commonly found in ex-warsaw pact and middle-eastern countries.
Physical Description Edit
GP-5 filters come in a olive-drab colored canister with a screw-on cap whose color varies on what batch the filter is. It features exterior markings that show the filter model, batch and year of manufacture and other markings on the top, bottom and on the inlet aperture itself. The filter weighs average and the canister, being metal, is prone to dents and scratches. The filter uses a particulate filter for aerosols, smoke and viruses and has a carbon bed for vapors and other chemicals. The carbon bed appears to be inside a cotton enclosure. The contents are held by a metallic frame inside the canister.
Asbestos content Edit
A lab in the Netherlands has seemingly confirmed the presence of asbestos in the GP-5 filter, in both the particulate filter, and the activated carbon.
The GP-5 Filter, despite its age is still being sold around the world and local distributors have them as entry-level filters.
