Disclaimer: Please note that not all surgical masks offer equal protection. As stated in the disclaimer, only ASTM Level 1 and above will filter 95% of 0.1 micron particles. China Standard YY 0469 masks only filter 30% of 0.1 micron particles, and European Standard EN 14684s do not filter 0.1 micron particles at all. This solution has not yet passed the CDC test method outlined in 42 CFR 84, but we are partnering with hospitals and national laboratories to get quantitative testing done as soon as possible.

About us: To help with the global shortage of N95 masks, a group of ex-@Apple mechanical engineers got together to #FixTheMask. We are creating an open source surgical mask brace — improving the sealing and filtration efficiency of standard surgical masks. But while that’s pending, we’ve come up with this DIY surgical mask brace as an immediate solution. This is just the beginning…
– A study performed by the Annals of Occupational Hygiene using tape to seal a mask to a mannequin face as compared to an N95. “All versions of the sealed [fitted] face mask were as effective as the N95 with insignificant differences after sealing“ https://www.ncbi.nlm.nih.gov/pmc/arti…
