Covid Mask with P100 filter connection and Exhaust valve

grabcad

Improved design of COVID-19 mask featuring a connector for approved P100 filters and an exhaust valve for exhaled breath. To assemble this design, cut out two circles of rubber for each inhalation valve and exhaled valve. The inhalation valve also requires a small hole punched in its center to facilitate attachment to the valve as seen in the photos. Meanwhile, the exhaust valve features a screw lid that only blocks airflow when inhaling, allowing air to pass through the filter instead of the exhaust valve.
