Make - covid mask quad filter

This is a dual canister mask using dual cartridges. Basically it utilizes 4 independent filters to maximize surface area.

This is a remix of two different designs.

The cartridges are from:

The Mask Body is from:

The body of the above mask was sized to 105%. Because of this, if you print the gasket, you'll need to resize it to 105% for it to fit. I personally get a good seal without the gasket. The gasket should be printed in something flexible like TPU.

Dipping the body in water at ~150 degrees Fahrenheit makes it pliable enough to mold to your face for a better fit.

Feel free to remix this. Personally I think adding a valve would make it safer, as you would not be breathing hot moist air into the filters. Valves are frowned upon because it does not make others safe around you in case you are infected. Maybe adding an option to filter the exhaust valves air would be the answer.
