I like this mask because it provides protection while allowing breathability, the straps do not hurt your face or pull against your skin, ears, or "tug" anywhere, and they are of a medical grade, quality, and engineering that I have not been able to find anywhere else online or locally. Thank you again!
So I have used both of the masks and what can I say other but great job. They work well; and the filters allow you to breathe easy. The KN95 masks work well and stay in place when you fit it correctly .
