CPAP Adapter for Filtration Mask
thingiverse
CPAP adapter to use as a filtration mask. This design is still under development and testing. I make no claims that this will protect you from or prevent Covid (or any other disease) in any way. the exterior diameter of the intake is .92" (23.37 mm). I have remixed the screw-on attachment from my Montana Mask. This way, one could use as a temporary filter Organic Cotton Round Makeup Remover Pads that are available at any drugstore. If you do wear this on your face, I would recommend frequently washing this in warm soapy water. Tinkercad: https://www.tinkercad.com/things/4VAXLeNNEzr-cpap-adapter
