Are they really NIOSH approved? NIOSH doesn’t approve KN95 masks[1]. Also, I thought elastic straps have to go around the head instead of the ears to obtain approval. Can we see the approval certificate? [1] https://www.cdc.gov/niosh/npptl/usernotices/counterfeitResp.html https://www.cdc.gov/niosh/npptl/usernotices/counterfeitResp....

You are right, I was mistaken, sorry for the misinformation! They went though the NIOSH modified testing protocol, not the official approval process. 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/MTT-2020-209.1_International_HenanFengzhihuang_HF-KN95-3_TestReport_Redacted-508.pdf 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.
