SUPERGUM NBC Gas Mask Filter, NATO Specifications, 40mm Gas Mask Compatible, CE Approved

Purchase at least one or more of these gas mask filters and store them alongside or inside with your gas mask. It is excellent for use against all 3 NBC dangers.

Dated as listed, professionally sealed. I really hope I never have to use them but they seem legit for the price. We'll probably grab a couple more in the near future.

Remember, these have a shelf life. You'll likely need more than one!

Hope I never need it but it looks proper like the others I have tested before this from the same manufacturer.

While it's difficult to know what you're dealing with on a jobsite, these work. When you don't know what you're dealing with, keep a mira safety nbc-77 filter on hand. Ive used these impertech filters and they work well. I'd suggest a dual filter mask. Even a brisk walk gets me winded as a fairly fit 160lbs male. It's like breathing through a straw. These are much cheaper than miras, but cover most of your bases
