Well, my kids too.
After some heavy sanding and finish on the cutting boards, I felt like crud. Vapor, dust - not good on the body without any protection. I had been without since I decided I hated the cloth style, and this was the first bit of sanding since. Picked up a P100 3M Pro series respirator and my lungs thanked me a bunch. Such a pleasure not being able to taste dust or get a headache from the vapors
Guess it was even nicer because i got it for $10 off. I won't go without this again. Question though, how do i know when to change the filters? Scanned the instructions but didn't see it.
