It doesn't look like these have passed ANY certification requirements.

Given the wide range of choices available, it seems unwise to go with something that's not proven. These are not certified either because they would fail certification...or because the company is fly-by-night and cutting corners.

I'd not want to trust my life under either circumstance...

What do you think about reusing surgical and N95 masks for multiple days? Does exposing them to UV light disinfect them?

Simply letting them sit for 3-4 days is all that's required. I number my masks with a sharpie and rotate their usage...letting any used mask sit out for 3 or 4 days before reusing.

So what about KN95 masks that are said to be ceritified: This KN95 face mask is Included in FDA Emergency Use Authorization List and manufactured by a certificated manufacturer Chengde technology Ltd,. Co. The filter efficiency of this KN95 mask is tested by NPPTL (National Personal Protective Technology Laboratory ) then prove it is over 95%, which can protect you in the critical time” https://www.amazon.com/gp/product/B08FBK52KY/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

Should I not trust this?

I absolutely would NOT trust anything from China. Just because it's on the FDA EUA list doesn't mean that 1) it's not a counterfeit...including the packaging, and 2) the company is still maintaining production standards.

Most officials branded 3M masks in the consumer supply chain in the US are currently counterfeit...the mask, the packaging, the certification claims.

Corrupt manufacturers can print whatever box they want to and have it say whatever they want until caught. And right now there seems to be no FTC or Customs enforcement in this area.

Personally, I ONLY trust the items coming directly from Korea because they seem to be enforcing legal standards. Even the FFP2 and FFP3 masks are increasingly coming out of China with what appears to be counterfeit packaging.
