MIRA SAFETY M Certified CBRN filter 40 mm NATO with Longest shelf life. 20 years

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!

Excelente calidad

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

Haven't had to use these yet luckily but great to stock.

Shelf life 20 years, way overpriced though.
