Review (2/5): ehh.
If you are just looking for a reusable hospital mask- this is great. But if you are looking for anything more - I suggest spending a little bit more for a better Vogmask. This one does not cover a huge surface area so can get out of place when talking or moving your mouth, it is not stiff at all so suctions to your face when inhaling and blows out when exhaling, and there is no filter so it get very warm and condensated inside the mask.
