📍WARNING—60%-70% of all KN95 masks imported from China do *not* meet NIOSH 95% filtration standard it claims. Some real—Yet many fake KN95s used by healthcare workers across US & world. You can’t tell what is real or fake (photo) by labeling. 🧵 #COVID19 forbes.com/sites/robertgl…
2) Key points on KN95 masks:
📌You cannot judge authenticity by its appearance, labeling, or packaging.
📌In instances, ECRI has received samples that, despite being labeled the same model, look slightly diff, and perform sig differently in filtration.

3) 📌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
4) Ear loops aren’t perfect, but it’s not ear loops that make them real or fake. Though neck straps better.
“The KN95 masks ECRI has tested all have ear loop retention straps. NIOSH has found that 9 out of 10 are equipped
with these rather than head/neck straps”
5) That said, it’s not Chinese regulations that are bad—same as NIOSH, it’s knockoffs.
“Chinese regulatory filtration efficiency reqs for KN95 masks are nearly identical to NIOSH reqs for N95 FFRs, but there is no guarantee that what you buy will meet KN95 filtration req.”
