My filters were delivered on Friday and I shot baits for a couple hours. I was using the "if you could smell it" standard.
1. By themselves they are not very good.
2. They are upgraded P100 filters that should be added to a base vapor filter.
I attached them to an expired base vapor filter on my mask and never caught a whiff of plastic smell.
So, I plan to use them with my base vapor filter and try to get extended life out of the base organic filter.
Note: when I'm done molding, I put my respirator is a large zip top food storage bag. It seems to extend the l8fe of the filters.
