Dustproof Masks - Activated Carbon Dust Mask with Extra Filter Cotton Sheet and Valves for Exhaust Gas, Pollen Allergy, PM2.5, Running, Cycling, Outdoor Activities (1 Set Blue Eagle, Dust Masks)

I use this for spray painting houses and it does great from keeping the paint breeze out. It also stays in place and doesn't move around while being active and doesn't feel hot like other masks.

A caveat about Covid. This mask has exhalation valves that allow free flow of the exhaled breath. That also allows free flow of your germs to others. For Covid, I blocked the valves with cotton wool to prevent them from opening. Mask is very comfortable with good clearance around my nose. The neck strap was a bit short for me, and fundamentally not ergonomically designed as when you raise your head the strap doesn't follow well. I cut those off and sewed on elastic bands to go around my head. 4 stars due to the strap issue.

The filter would bunch up at the nose (slide down) and would ultimately not seal like it should. I tried several different ways to try to fit it on my nose with the nose crown bit even though the mask would stay, the filter always slid down and leaked.

The smell of the inside is so bad it couldn’t be worn long enough to break it in and get used to it.

I was never able to get it to fit, or work. I asked friends to help. They were unable to make it work. I will be giving to a larger person.

Forms to face, even with my beard

Like the product, however it doesn’t filter everything.

Great for my wood shop
