Mask Concept

A mask concept for TPU (you can print it rigid it'll just be less comfortable). Loop together as many rubber bands as necessary. If you print this let me know how it fits, feedback can lead to a better universal fit. If you're handy with CAD you can immerse yourself and use the waterline to create a custom fit, float something next to your face for scale.

I'm no expert on what material would work best as a filter, but the advantage of this design is that you can layer different materials easily with no need to sew.

Not an expert on anything, feedback appreciated.
