Because if you don’t have some way to protect yourself from chemical, biological or even nuclear threats, your storeroom full of food may well be useless. Gas mask filters are one of those indispensable items any prepper worthy of the title needs to have in his or her stockpile. But the gas mask alone won’t do much unless you have the right filters. 3m doesn't have comparable CBRN/first responder and LE oriented products so maybe they'll keep some of them in production.So you did your homework and picked up the ideal gas mask for your purposes. ![]() Now that 3m bought them out I don't know what is going to happen. Scott's are the best filters (and full-face masks) around IMO. Most 40mm masks like the M40 have switchable filters, so just need to take the port plug or voicemitter out of the other port and use both.Īll of the above. Those large pancake P100s I'm not so worried about, but if you try to use a chemical cartridge you will have more breathing resistance and possibly reduced protection. Something to keep in mind is that those filters are designed to be used in pairs. ![]() It's pretty sad when people know "mira safety" but don't know who 3m is.ģm 701 is a good solution. I hope that's a joke, 3m is a huge multinational corporation and one of if not the largest manufacturer of safety equipment in the world. You would probably be better off to just buy a new 3m, MSA, etc mask with modern bayonet mount filters. In 40mm, they are usually listed for PAPRs instead of masks.įor spare parts for your M40 you should look at MSA, their Millennium masks use many of the same parts. If you are looking for virus protection, if you can find a P100 only filter it will be easier to breathe through and weigh less, and probably less expensive. Why does every gas mask/respirator thread now have links to a previously-unknown skam-ish prepper supply company?Īny 40mm NATO/EN/CE threaded filter will work with the M40. I already have filters as I use a 3m half mask pretty frequently. The set that I have I'd feel safer if I replaced the orange seal also. I was actually looking for those and could only find them listed in a case quantity, if you happen to see them somewhere. Most 40mm masks like the M40 have switchable filters, so just need to take the port plug or voicemitter out of the other port and use both. Adapters have a 3 lug bayonet style attachment and you dont have to unthread the adapter when changing filters. They come in 2 packs of both filters and adapters so if your mask only takes 1 filter, you could get 2 masks with 1 package of each. It fits 2091/07000 p100 filters onto a 40mm thread, and mine reads 701B inside the adapter. Also, check the straps to see if they are still good and flexible, or worn out and loose.ģm 701 cartridge/filter adapter. ![]() Most average CBRN rated filters with average 5 years shelf life sell for $50-$60, which is the going rate.īy the way, check the seal on your mask by pressing it against your face, holding the palm of one hand over the unplugged filter hole (or over the face of the filter if one is installed) inhale and see if any air gets through or the mask presses up against your face from the negative air pressure (which it should if the seal is still good). They sell for about $90, but, no other filter filters out smoke and carbon monoxide with shelf life of 13.5 years. I especially like their VK-450 smoke/ Carbon Monoxide filters which protect from CBRN threats as well as smoke and carbon monoxide (the only filter I've ever seen that does so). I have purchased a lot of recent filters and other related products from this site. Some of the standard CBRN rated ones are good for 5 years and can be purchased from various online sources like Botach, LA Police Gear, and others. Some of the newer ones like the Scott filters are good for 10 years and the European ones for 13 up to 20 years depending on the model of filter. All filter canisters have a shelf life and most of the common older ones are only good for 5 years. ![]() I have an M40 gas mask and it takes the standard 40mm filter canisters.
