Filtered Face Mask
A 3D printable face mask with a tight fitting filter cover using a replaceable cloth type filter. Made for the Covid-19 epidemic amongst us.
After 3D printing the mask you'll need to seal it with epoxy or enamel or something else to make it air tight as FDM 3D printing isn't air tight. I assume the other 3D printing technology isn't either but FDM printing certainly isn't.
For filter material you should use something that can filter out down to 3 microns. I cut up an air filter designed for a house's air conditioning system. I got one with an MPR rating of 2500 which is equivalent to about a 13.5 MERV rating with an efficiency of about 96.5%.
The inner filter box cover is a tight fit with the material caught in between, too thick of material and it may not work. You will have to resize the cover if this one won't work for your needs.
You can also try cutting enough material to cover the entire inside of the mask though I don't think that's necessar
