Pros: 1. Seems to work as expected. 2. Easy to get on and off. 3. Easy to breath in. 4. Filters ate standard 3m shapes so easy replacement. 5. I like the vent for fresh air (though I sometimes forget to close it and start breathing in bad things). 6. Customer service is amazing. I knocked off the filter cover and ran over it with my tractor. Asked a question on this listing about buying a replacement. Customer service sent me a whole new mask free of charge. It was unexpected but fantastic.
Cons: 1. Mask was comfortable for me, but hurt the bridge of my wife's nose. 2. You will sweat, a lot...but That's probably true of any mask.
