Air moves around the filter and not through it
Edit: I am NOT looking for a discount. I was looking for a mask that would keep me safe on an airplane. I do not feel like the airflow into this mask is safe. The bottom strap that would go around your neck is so loose it does nothing. The biggest problem is that air comes in from around the filter so it is basically ineffective. I took off the clip and covered the hole with the filter and it filtered so well that I could barely breathe. So the mask basically does nothing. i’ve tried cutting out a new larger filter but the little spikes in the filter holder push it up and air can get around the filter, no matter the size. This mask will not keep you safe from Covid in anyway at all.
