Snorkel Air Filter

thingiverse

This video shows how to turn a full-face snorkel mask into a reliable respirator with replaceable DIY filters made from any material. The design of this filter is unique because it has a larger surface area than other designs, which results in less resistance when breathing and therefore less damage to the lungs. I create these filters using PLA filament and print them at 0.4mm layer thickness with no support using the default Coarse setting in Cura.
