MIRA SAFETY MSingle NATO NBC 40 mm Filter

These are good filters, but note that they ARE NOT rated for radiological or chemical warfare agents (you need the gray $80 one for that). However, these normally cost right around $45/ea. They are on sale on many sites for $29.99 because they are old stock manufactured in Oct 2020. Still a good deal, especially if you're using them now and not buying for SHFT storage. But I'd rather have old ones than none at all so I think it makes sense to get a few while they are cheap. I'm not sure what exactly goes out of date on a filter like this.Here's what Mira Safety's website says: "IMPORTANT NOTE: The current batch was manufactured in 10/2020, with an expiration date of 04/2028. This product is currently on clearance and will be discontinued once all units are sold. For that reason, they are offered at a deep discount.

Title says it; tried it on when cleaning out a freshly rotting squirrel corpse from my storage shed outside on an msa millenium mask, not a single smell came through. Tried aerosol protection by spraying copious amounts of febreeze and lysol in a 4x5 restrooom and testing for scent and taste after 10 minutes- once again nothing. I'd say it's fine. Goofy tests- sure- but they work.

These are newer/new production. Better to have them and never need them, than to need them and not have them. I lucked out on one of them and got it on a lightning deal ( $25 ish so that would be nice more often ) I have brought 3 of them so far.

The product is as described with the exception of the shelf life. They say this has a shelf life of 7.5 years. That’s accurate, except when you get it, it’s already 1.5 years old. Mine was manufactured in March 202, so getting it in August 2021 means I’m already down 1.5 years. That’s annoying as I now only have 6 years of shelf life.

Ordered in the AM , was delivered the same evening. Super happy
