If you like breathing and long life, this mask is an excellent choice. In construction reviews for masks, this one was one of the highest scoring. Plus, the replaceable filters allow you to select the right filter for the environment you are working in. Used this mask working in an attic where the dust and fiberglass fibers were a considerable problem, making anyone working there cough for days after just an hour working. Pros: the mask is comfortable and does wick moisture away from the face, making it more comfortable in a hot environment. Mask seals better and protects considerably more than ordinary "dust masks." Definitely protects the lungs and throat. Cons: the filter packs tend to pop out easily. You have to angle them in just right when putting the mask on.
