Bests & Worsts Reviews from Amazon

We decided to try to get stocked up on some emergency supplies early this year, especially as the weather gets colder in our area. I went with this set of masks because the lab testing documentation they were able to provide, and because of the sleek black color. So far, I have been very impressed. The masks fit very nicely on my face, and the almost duck-like design provides an air cushion between the mask and my nose and lips so I don't feel like I'm suffocating. The masks have an adjustable nose clip to help you get a better fit on your face. With each breath I notice that the mask almost inflates and deflates which leads me to believe that the air is ACTUALLY being filtered and that there are no gaps or holes in the mask. Just recently I wore the mask for almost 6 hours straight and felt very comfortable.
