Dodarhip 40mm Gas Mask Filters - Full Face Respirator Mask Cartridge for Organic Vapor, Paint, Spray, Dust, Epoxy Resin, Welding

This gas mask filter fit my gas mask which I use to keep out the smell of paint when I'm in a small area. If you need an extra filter i recommend this one.

I am happy to report that this refill respirator cartridge fit my mask I have very well.We got a mask to two for emergencies intitially but now I am working in the garage with wood and chemicals to make furniture - this is a good thing to make money - not so good for the lungs.I am using the mask regularly now and needed a replacement. These work great with my existing mask - and I guess the connection is standard fit?Very good replacement -Recommended

This 40mm filter fits all masks that accept a 40mm filter. It came shrink wrapped and boxed. My filter is marked with a May 2022 production date and says the expiration date is 5 years. It's made of plastic instead of metal, but that doesn't bother me. It's not cheap/thin plastic. If I slam my face into anything hard enough to damage this filter, I think I'm going to have bigger problems.I haven't disassembled it but if you shake it you can hear the loose activated charcoal inside. These are sold for organic vapor use, not NBC use. Although I would certainly use this for NBC if I had nothing else available. When using with organic vapors, expect this filter to reduce but not remove the vapors completely. It's an entry level filter, not a high end air purification device. I think it works fine with the proper expectations.

Filter came with some kind of manufacture defect where the two halves come together allowing for outside air to bypass most of the filter, tested with gasoline vapor, ineffective, spray paint vapor, also ineffective, the only thing i would trust this for is a prop to fit old Russian masks.

I got this to have in situations where I work with really stinky paint fumes. I have only used it once so far, but it seemed to do well with blocking out any paint fumes, so I am inclined to say it works well.
