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

From the moment I opened the package, I knew I had made the right choice. I was genuinely thrilled—it was exactly what I hoped for (maybe even better)! The quality is outstanding, the details are spot-on, and you can tell it was made with care.I’ve been using it every day since it arrived, and I can’t stop recommending it. It brings a smile to my face every time I see it! If you’re on the fence, don’t hesitate—this is absolutely worth it!

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

Very high quality product. New, not cheap surplus.

As described

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

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

Unfortunately we are living in different times and one must take certain precautions. Purchased two of these to go with the CBRN gas masks we already own. I have little faith in surplus masks or the filters since there is no way to tell how old the items are or how they have been stored. Ratings for these filters have been good and the life expectancy of these units is very good as long as they are properly stored. One of the few purchases I have made in my life that I hope I will never have to use but know I have them if needed.

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