Fit north masks great. Filters work good.

Fits the N95 mask I had perfect

Make sure to replace your HEPA filters often. These units are very good for the amount of dust they can stop and how fine of a dust they stop, but be sure you change them out often for your safety. The cost of these is cheaper than any hospital bill and a must have if you use air purifying masks. IF YOU DO NOT KNOW HOW TO USE THESE OR AN AIR PURIFYING MASK, DO NOT USE IT. Go get yourself educated before you use any air purifying mask.

works well

I have this and the fabulous but heavier Honeywell North 75SCP100 Combination Gas and Vapor Cartridge (2-Pack) also purchase from Amazon. I find the North 7580P100 Particulate Cartridge (2-pack) much lighter the vapor combo blocks smells better. I use these filters with my half mask. The durable masks are given to hospital workers at TCID are called North 7700 respirators and they’re much more effective than N95 masks. Unlike N95 masks, which filter 95% of particles larger than 0.3 microns in diameter, the P100 cartridges used in the North 7700 masks at the Texas hospitals filter out 99.97% of particles. This is that filter.
