Honeywell N P100 Particulate Filter Cartridge

Recommend!! Work as it should

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.

I was sent cartridges from some subsidiary brand, which would be fine as long as they fit the Honeywell 5500 mask l, but they don't. So they are useless. They don't even match the picture. False advertising

These were exactly like the ones that came stock with my P100 mask when working in the ICU during COVID. Highly recommend.

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.

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.

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

Great, affordable product
