Bests & Worsts Reviews from Amazon

This was worthless, I wore it for only half an hour shoveling the pictured sawdust and the inside of the filter was full of sawdust (pictured). I had it as tight as I could get it with a brand new filter and I was still breathing dust. It also would not seal around the top of my nose and caused a jet of air to travel up my nose directly into the corner of my eye with every exhale which just blew dust right into my eyes too. Don't waste your time or money with this.
