Sorry to say I can’t breath with this mask on. It has a pocket on the inside to allow you to place a filter in. If I place the filter it’s so thick it’s impossible to breath. Even without the filter it is still difficult to breath, especially if you are walking or exerting even a moderate activity. The inside pocket is loose and sticks to your face as you breath in. On the whole, It seems the material is too thick, and not porous enough to allow you to breath effectively. So it’s a no from me. 👎🏻 I’ll stick to my disposable surgical masks for now.
