cotton pad face mask with downward-facing filter port

thingiverse

These extended cotton-pad face masks are really cool, but I wish the filter was located at the bottom of the mask so you don't breathe directly onto the pad. My reasoning is that it will extend the life of each pad. It also has a pretty funny effect - it makes your nose and moustache look bigger. Just remember, I'm not a doctor, so use this information wisely.
