exhaust fan! Draws air out of the mask

The fan on this mask works in reverse compared to other air purifying masks. No mask completely seals a person's face. By sucking air out of the mask, a negative pressure is created in the mask. This will pull contaminants (and viruses) into the mask through the edges of the mask. I prefer the opposite. A mask that creates positive pressure by forcing filtered HEPA air into the mask to ensure you're breathing filtered (and cool) outside air, and pushes out pollutants from inside the mask.

Pros
  • Anti-fog
Cons
  • I will add later
