HEPA Covid Coronavirus Face Mask

Important! Note that most HEPA filetrs are not very effective against Coronavirus, since the most common size is .3 microns, when the Coronavirus is said to be .1 micron in size. That said, even a lower quality filter prevents the wearer from spreading droplets around. Two sizes included; 10 and 12 cm height. This mask is, presuming you change filtration material, or is the filtration material heat-resistant, REUSABLE! If you do not have a HEPA filter on hand, you can also use other filtration material, just be careful that the entire airflow is channeled through the filter. For greatest protection, use hot glue or silicon gel to further secure the filter material to the edges of the frame. No supports needed!! for PLA select 20% infill, for ABS and PETG (which I recommend, because of thermal resistance -> high temperature disinfection options) is 15% enough. We recommend an acetone finish, should you choose ABS. The goal is to make the material as smooth as possible, which should help with disinfection.
