How to clean a GP5 gas mask after purchase

Hi. I've made this quick video about gas mask cleaning since sometimes i see people unboxing old masks from army surplus and straight up putting it on their face after being stored for decades. That is no good. I've done that when i was 11 and got a huge (and rare) eye + nasopharynx infection. I don't want that happening to you. Also, the whole video was shot by hand on my camera since i don't have a tripod, so i am very sorry for the shaky part at the end. DON'T EVER THROW GAS MASK FILTERS TO GARBAGE. Thanks for stopping by, S.T.A.L.K.E.R.
