Develop and validate a low effort contamination free means of n95 reuse than does not increase the burn rate of other difficult to substitute consumables (eg gloves and calstat) Not sexy. May be irrelevant in 3 weeks at crisis standards. Right now with the supply chain as is and attempting to surge standard of care capacity this is the thing that would be useful. If we cannot manage ppe lack of providers will make lack of anything else moot. |

As an Earth scientist, I could imagine a mineral based replacement for the filtering part -- e.g. something like a zeolite -- but the lack of mechanical flexibility and the risk of silicosis are two serious problems with that right off the top of my head.
How about 3D printing of filters? Can N-95 -- 95% of particles greater than 0.3 microns -- be achieved?
Edited to add: It appears somebody is doing this for liquid filtration: https://liquico.com/products/
