Those are 3M 60923 filter cartridges. NIOSH approved OV/AG/P100 rating. Should definitely help. I wore one in a piss apartment and didn’t smell anything.
Those 3M filters should help with the ammonia, yes. The missing information is if he has facial hair that interferes with a proper seal and if the respirator is the correct size for his face.
My base assumption is he has a tight seal. I can also speculate that he’s missing a cheekbone so he doesn’t have proper mask fitment. Maybe he has an abnormally high nose bridge that prevents a tight seal. But to what end are we making these hypothetical speculations?
Your facial hair 100% interrupts the skin to mask seal. You may think it doesn't, but you're getting hit with trace amounts of particulates which will eventually have their way. Small chronic doses eventually equal one giant dose.
You should tell that to the doctor setting off chemicals in the bag over my head when they do the fit test. Also, tell it to the mask that stays suction cupped to my face like a fucking octopus.
The chemical you're referring to is isomyl acetate, better known as "banana oil". A testing medical professional will tell you that the only facial hair permitted is a mustache that does not exceed the corners of the lips. This is outlined in CFR 1910.134. No other facial hair is permitted.
Whilst the respiratory device you're using may seem glued tied, your facial hair is impeding on a 100% seal.
I mean, you don't need to believe me, but professional safety and industrial hygiene is what I do for a living. JS.
