Beats Having to Wear Two Masks
I bought this mask because I didn't want to have to start wearing two masks at work and this one is 4 layers with filters you can add inside.  However, it is kind of hot and stuffy, more than my regular masks.  It also had a tendency to slide down off of my nose and I was constantly having to adjust it.  As masks go, it's not a bad one.  It's just not my favorite.
