Review on 🔒 Enhance Your Safety with M View Global Protective Certified Individually by Anatoly Yorgason

Fits my narrow, medium sized male face very well, I think as accurate as you would expect from a boxed mask. Decidedly block the air a little but cause no discomfort. I can filter better than a plain blue "surgical" mask. Also, with repeated use, the odor from the mouth doesn't seem to accumulate like the blue ones can. If actually blocking the virus equals blocking the air, an effective product.
