What Are Our Objectives?

  • Three components:
    • Comfortability
      • The main problems of headaches, carbon dioxide inhalation, and skin irritation [1] are caused by the tight seal. To fix this, we plan to implement a foam lining around the edge of the N95.
    • Durability & Cost
      • 3D printed mask extenders can be cheaply produced and will further reduce discomfort. The foam will be cheap and can be produced rather quickly and cheaply.
    • Oxygen Circulation
      • The masks are linked to breathing restriction and we’ve considered adding an oxygen filtration system for those who have previous respiratory problems. [2]
