3M Respirator with valve
"I use a black patina on my metal clay creations and then polish most of it off with radial bristle brushes. The fumes and debris was really irritating my nose and decided I really needed more than a flimsy paper mask. Turns out the 3m Respirator is comfortable and eliminates any nose irritation. I really think it does an A + Job of filtering the air. So I am glad I bought this!"
