Kn95's are being tested it seems, and they are failing.. ─ ECRI testing of imported FFRs has revealed that 60-70% provide only sub-95% filtration performance.

Kn95's are being tested it seems, and they are failing..
─ ECRI testing of imported FFRs has revealed that 60-70%
provide only sub-95% filtration performance.
■ This trend aligns with what NIOSH has found through
their own testing; as of September 2, 2020, 53% of
the 358 FFR models tested did not meet N95 filtration
requirements

- levpopov 6y agoThanks for linking to the report, it's interesting reading. I think it largely confirms the point of my post though - we need independent certification labs in the US to make imported PPE usable. It is unclear what % of reported quality failures in that report were due to counterfeits. Now that the manufacturers have authenticity codes on their product we can hold manufacturers directly accountable for filtering performance.

I agree, but we've seen that be corrupted by profit-seeking
