A comment on Electric cooker an easy, efficient way to sanitize N95 masks, study finds. Parent comment
They have been tested for respirator filter efficiency only and were found to exceed 99% filter efficiency: https://www.cdc.gov/niosh/npptl/respirators/testing/results/...
But they are explicitly not NIOSH approved and as mentioned have an ear loop design whereas seemingly all approved masks go around the head. Wish I could edit/remove the original posting.
