Thought the mask was in front of me to protect me puke when it came to removing cat urine, animal carcasses and emptying the compost bin. And it works well. One does not even notice. Even if one scrapes times as something exotic like paints under 800 degrees can smell nothing. One can also easily breathe topsy-setting will also work properly while you are wearing them. Also compatible with goggles and ear protection. Best.
