Happy to report that we’ve developed a 3-D printed mask. Passed N95 equivalent fit-test with Bitrex (surgical wrap as filter, readily available). Wearable all day. Mask can be resterilized/reused. Nylon-12. Thanks to @Intermountain3D for co-development. #COVID19 #PPE

Credit to Dr. Bruce Spiess from @UFHealth for Halyard H600 two-ply spun polypropylene filter idea. Works great in our testing with no shortage.
