COVID-19 Emergency - Using UV Lamps to sanitize Face Masks overnight
KeepItSimpleStupid:
The photo shows 2 levels of lines to hold the masks. That appears to be missing in the words.
there is also a 7 fold safety margin. Based on the location of the sensor, it looks like more than.
So, should I make one at home from a cardboard box lined aluminum foil and an HVAC UV-C bulb?
They only get 3-5x, but they wear the mask the entire shift. I have a few N95, non health care masks 3M 8211 at home and a half-face non disposeable respirator.
UnaAllan:
I guess you can desinfect masks with the sanitizer or just wash it in the machine with high temperature
KaneTW:
No. You cannot. That ruins the mask's protective properties (for a N95-type mask)

Since this is an electronic forum - what about RF at a resonant frequency which destroys the virus?
I found this article where about 60GHz was effective for their sample, but its a bit old.

That's not RF but light, modulated at 60GHz. Microwaves are absorbed too easilly by water to be effective. No details are given, but it's a much higher frequency (near infrared to visible) modulated with 60GHz. Anyway, it sounds like something which works in the lab but is of no practical use, at this stage.

I use this myself. ;)

It looks like a fake to me. Test it by putting a banana quite close to the LEDs. If it turns brown, then they're genuine UVC LEDs, otherwise it's fake.
Sadly, most LED sterilisers are fake. That looks like a dodgy site. There are no safety warnings about any of there products, because they're all fake. Real UVC sterilisers emit dangerous radiation which can burn the skin and eyes. Fake UV sterilisers, emit UVA, visible violet, or blue light, which is safe, but useless for disinfection. Return it and demand a refund.
