Make - covid mask quad filter

thingiverse

This is a dual canister mask using interchangeable cartridges that maximize filtration surface area with 4 independent filters. The design is a combination of two different concepts. The cartridges used are sourced from this Thingiverse model: https://www.thingiverse.com/thing:4273090 The mask body is based on this Thingiverse model: https://www.thingiverse.com/thing:4242190 Due to the oversized body, which was scaled up by 5%, the gasket will need to be resized accordingly for a proper fit. Alternatively, printing the gasket in a flexible material like TPU can help ensure a good seal. To achieve a better fit, dip the mask body in water at approximately 150°F before molding it to your face. Feel free to remix this design and consider adding a valve to improve safety by preventing hot, moist air from entering the filters. However, be aware that valves are discouraged as they can pose a risk to others if you're infected. A possible solution could be adding an exhaust air filter option.
