I won’t know until I use one but they seem authentic good quality

This gas mask filter, built to NATO specifications, boasts a 10-year shelf life and claims comprehensive protection against NBC threats, smoke, and particulates, even in low-oxygen environments. It's designed to transform a gas mask into a multi-use smoke hood. I haven't had the opportunity to use it in an emergency situation, but its specifications and long shelf life offer potential peace of mind for preparedness.This review represents my personal opinion and experience with this product.

works amazing with the right gas mask. Was blasting spray paint in a VERY enclosed space for 45 minutes and didn't smell a thing.

Good quality filters. Thanks

Okay first up, obviously I haven’t tested this thing. I’m not out here getting tear gassed on the daily, and I’m not about to waste a perfectly good filter by opening it. Most of these filters are the same on the inside anyways. That being said, the outside of this filter is a nice, durable metal. I bought these as a backup to my Mira Safety filter but I think these might be just as good quality if not better. I am solely basing that off of the external construction quality. Overall you can’t go wrong with this filter for the price.
