With low breathing resistance and compatibility with all standard 40mm NATO masks, the NBC-17 SOF ensures clean air when you need it most—without the bulk.

Watch out for the Date of Manufacture

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 I'm not sure what exactly goes out of date on a filter like this.Here's what Mira Safety's website says: "IMPORTANT NOTE: The current batch was manufactured in 10/2020, with an expiration date of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.

Arrived same day as ordered.

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

I'm not planing on living much longer if I have to use this anyway

Seems good, obviously I haven't broken the seal so I'll just have to figure out if it's worth the money when I'm being gassed for whatever reason.

Works against aerosols and scents

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.

Great gift idea

It’s a great gift for the outdoors man, I don’t have a gas mask, to use it. Thank you for a great gift idea
