Home Depot: 3M P100 Filter – Professional Multi-Purpose Respirator Mask Black Drop Down $20.1

Need a respirator for home use. Looked around and found this to be the best deal from a reliable store.
Caveat, I’m not a contractor but from the looks of it, a 3M mask with a set of 3M P100 filters for 20 bucks is a steal.
