We used dry heat at 100C for 30 min to treat 3M model 1860 N95 masks at Stony Brook University (Long Island, NY) and confirmed that this could be repeated over 4 cycles, with no detectable degradation of filtration capacity as measured by quantitative fit test of 300 nm particle exclusion. This also works for model 1870 masks.

Both model 1860 and model 1870 masks failed fit testes after autoclaving at 121C.

We used a high capacity medical grade oven but dry heat treatment could be performed in a pre-heated conventional (non-convection oven). Important to note, however, that 1860 masks are degraded at a higher temperature (121C).

Nice update.

But there is no proof that this is viable yet as stated in the report.

We need to get something to work with that is proven to work.
