There are two styles of Filters for the Czech M10 style masks. The ones sealed in foil (Tin Foil)they are NBC rated, The ones in the clear bags are for gas only I am told.. I may be wrong on this but people seem to get a mixture of both kinds when they order in bulk from other vendors. Just keep this in mind. If you have an M10 style gas mask, these extra filters won't last forever. I love my M10 masks and have a pretty good supply of both styles of filters on hand. When you order, ask KS if they are foil wrapped or plastic wrapped.. Also practice changing these filters out. Does not take as long as some people say after you have done it 5 or 6 times. But the mask has to be removed from your head to do it.
Nice back up's.
I don't think these will help in a real disaster. But they work great for painting, and working with household chemicals like bleach and ammonia (keeps the smell down). Only down side is they are hard to install in to the Czech M10. But that is a problem with the design of the mask not the filters. I don't know the quality of these yet, as I am still using the filter set that came with the Czech M10.
If you own the Czech m10 or the US G17 you should buy extra filters. Especially when you know they are new and unused!
They fit in my polish mp4.I don't intent to test them against some of the things that it protects from but hope that in a bad situation it will provide at least some protection.
This is a great product. These are well kept and still sealed to protect the filters. When you get these put them in a airtight bag with oxygen/moisture absorbents to give these a indefinite amount of time.
Thanks for another great product.
As a side note, these filters are still very useful but be sure not to open them and store them right. Never know when you may need them.
