SUPERGUM Gas Mask Filter, CBRN 40mm, Certified Gas mask Filter | Long Shelf Life

Packageing for shipping was adequate, and all filters well sealed.

Hopefully they work when needed. They are packaged well. Appear to be genuine.

This is an excellent filter that allows a nice flow of fresh air into my PAPR mask while cleaning out dangerous particles that might otherwise enter my lungs from the welding and grinding processes I am involved in. I love my lungs. I keep them very close to my heart. I caress them every day. Something so important to me must be cared for with the love and respect that they deserve. So, I have a PAPR device to protect my lungs when grinding and welding. I love to grind and weld metals almost as much as I love my lungs. This filter is a replacement to the one that came with the PAPR mask. The original one did its job very well. I had been unwittingly exposing my lungs to fiberglass fibers. I was using fiberglass welding curtains around my welding booth. The original filter caught a bunch of the fibers right out of the air, and you can see them in the filter. I have since gotten rid of the fiberglass curtains and replaced them with welding curtains made from a translucent material.

I use for painting and works well.

I was reluctant to order these after reading some of the reviews, but I did finally order two filters, and both arrived fully vacuum sealed and intact with no issues. As these are emergency items, I can't review their effectiveness at this point. I am pleased with my purchase.

I've read several complaints of holes in the vacuum shrinking so I was a little worried that I might receive the same. But this first one that I received appears to have an excellent vacuum on it. Maybe the unlucky few were more likely to post reviews. I hope the rest I get come like this. :) Update: The next 2 filters came without a vacuum seal. I'm sure they will still serve their purpose if needed but a vacuum seal would definitely improve shelf life.

Haven't had a need to utilize the filter yet but it arrived sealed and intact. I put the sealed filter in a vacuum bag with my mask and sealed them both for future use if needed.

I use these for my consulting firm so they MUST work. To those worried about the foil vacuum sealing I talked directly with the company engineers. They told me the vacuum packed silver foil is simply packaging and has nothing to do with the shelf life. The ones they ship to the military dont even have the foil packaging and still have a 20 year shelf life. The shelf life of 20 years is for the canister and the 2 seals on the canister itself. If the two seals on the canister are intact the 20 year shelf life is intact. The following was their direct message to me "All the filters we supply to armies around the world are not supplied with the aluminum packaging. Some customers ask us for another case of this type. I would like to bring to your attention that if the plastic caps on the filters in the front and back are intact then there is no fear that the filter has been damaged and therefore its expiration date remains the same."

Perfectly sealed. Impressive.

Im very happy ifs a good quality filter and was delivered on time

In sealed packages. Hope I never have to you it.

Package came broken. Lost its seal. Basically unless
