N P100 Particulate Filter Cartridge

Exactly as advertised, works extremely well. Bought before all the Covid problems for about ~$8.00 a pair. Unfortunately, Amazon seems to be allowing vendors to price gouge by quadrupling prices. While I recommend the product (way better than paper masks, paired with North 7700 respirator) beware of gouging.

I have a North half-face medium, and these fit as expected. I wish these had been in stock when I needed them -- the California wildfires last year made the air pretty bad in this area. But at least now I have them, if the coronavirus thing really gets dicey. As a substitute for those N95 things that nobody has in stock right now. You should be able to get these things at industrial safety stores, but those stores are not typical destinations for me.

Recommend!! Work as it should

We purchased 2 of packages of these for my business thinking they were a Honeywell P100. They didn’t fit so I happened to look at the package and it said Stern on the instructions. Do not buy.

Exact replacement to the one that came with my mask. Fit good and works good. Shipping took longer than I liked but was cheaper than buying it at the store.

Great, affordable product

not fit on the mask I bought from Amazon at the same time. >>>>> It was not enough information for the mask that I bought to get wright filter

Same filters we used in the Air Force for sanding aircraft, work great for demo work on my house. A lot better than wearing a standard dust mask or N95.
