MIRA SAFETY MGas Mask Filter - Certified CBRN Filter for Full Face Respirator Mask, 40 mm NATO Gas Mask Filter, Longest 20 Year Shelf Life, Vacuum Sealed NBC Filters, Compatible with Mira Gas Mask

Very high quality product. New, not cheap surplus.

I bought this 40 mm NATO NBC filter for my Avon cm50 works pretty decent it does stick out a little bit but that's because this filter was not designed for the cm50 it is in the sense that it is the same thread size 40 mm NATO but however you want something more compact because you have a Avon cm50 as well I would recommend trying to find the actual Avon 40 mm NATO filters but all in all if you're just trying to get anything you can get your hands on that is 40 mm NATO and has NBC protection this is your best bet

As described

Haven't opened, but it has a great vacuum seal and hope it works if I need it lol 👍

The Amazon description says MIRA SAFETY M Gas Mask Filter. The product name says VK-530 and the about item describes it as the VK-450.I took a leap of faith an purchased it on the accompanying pictures, and it turned out to be the one I wanted, which is the MIRA SAFETY NBC-77 SOF

If only the gas masks came the way as the filters. The filter I got is great.

Make sure your filter does radiation.

Should save your lungs in a time of need
