Love it

Buen material

I bought it as a replacement, it does what it should.

it will work

I laser Anodized aluminum and various painted surfaces, which often creates a (toxic) smell. When i had this filter installed in my mask i didn’t smell or taste anything. I breathe easy and clear for several hours in an otherwise toxic air environment. These screwed right in to my mask, extremely easy to use, snugged up great, and provided me with fresh, filtered quality air. These filters Performed fantastic! Excellent filter for the money. I’ve purchased several more and will continue to use them!

Fit perfectly with my surplus GP-5 gas mask.

Filter fits my mask perfectly, as advertised. No chemical attacks recently, so can't speak to that!

I ordered 4 of these this month, and one of them was defective, as it wasn't air tight, and also let air in through the top, when it was on the mask. So buyer beware! You might buy multiple, and not get as many as you want.
