Love this new dust mask it's so soft and flexible it fits perfectly on my face and feels very comfortable unlike those disposable ones they sell at the hardware store. It has plenty of holes for ventilation which adds to the comfort I like it that I can wear it for a long time and not feel sweaty or like I can't breathe. The mesh all around and the activated carbon do a great job of filtering the air definitely a great mask and after trying this one I'm definitely not going back to the other uncomfortable disposable ones.
