Does anyone have info on quality UVC devices for personal use?

with alcohol wipes does kill covid.

I've read of school systems putting in UVC systems to protect against covid. Might have been Colorado, can't recall.

Hospitals use UVC to disinfect.

I have heard that orthopedic surgery suites/operating rooms use them to kill germs.

If you get the ones that go inside the air vent ducts it may work.

That's what I'm concerned about, buying junk or ineffective units. Ty!

Inside a duct, the intensity of the light could be plenty high, because there's no risk of exposing people.
uV will destroy any virus, in the presence of air, by radicalizing double bonds in some the RNA nucleic acids. They fracture, and rapidly oxidize, ruining the reproductive code.
But, light intensity & time are reverse correlated.
A low intensity light may work, but in hours, not minutes or seconds.
In a duct, they could use a very intense light source, because people's eyes & skin aren't at risk.
And, since it's an installation, the current flow needed would be coming off the building's power, not a few D batteries.
I'd rather just use ethanol or a quaternized sanitizing agent.
I wouldn't trust these things. False sense of confidence.

it zippers closed. stands up on its own but has soft sides.

with lights on top and bottom and a rack in the middle. cost about $100.

use it for masks, phones, air pods, wallets, credit cards, glasses, etc.

Nice because I don't want to hold a wand for 30 seconds over an object. Also UV light is bad for your eyes.

Just plop items in box, turn it on, walk away, let it run. 90 second cycle. Mirrored interior. Light coming from all directions.

Certainly I can't prove that it is killing viruses. But I figure I will give it a shot.

The mid to high range of 'C' rays I think.

Yuck and Yuck

It's a hand-held unit (4-AAA batteries). The reviewer compared it to another that he had received, and this was MUCH stronger when he exposed the dosimeter card. Been watching this guy's YouTube videos for a while, and he's pretty straightforward and reliable.



(There's some preliminary discussion and stuff...product testing starts at about 5 minutes into the video.)

The spectrochemistry doesn't work for me.
With 4 AA batteries, I have my doubt overall light intensity is sufficient to trigger the free radical reactions that result in viral denaturation. Certainly not in short time exposures.
10 second exposure to ethanol, or a standard consumer sanitizing cleaner, is proven to work, pretty cheap, and not that inconvenient.

The decomposition mechanisms (except for one) require free radical formation, typically at a carbon-carbon double bond or an acyl group.
The formation is exponentially proportional to intensity (photon energy & amount of photons).
1/10th the photons leads to 1/100th of the radical formation. And, so on.
My dubiousness remains.

Sorry, but without knowing the exact frequencies & light energy emitted, I still question that these can achieve radicalization of the needed functional groups, and over what time interval.
What band & what power?
I simply don't believe something driven by AA batteries would supply the per second output to trigger those reactions.
I haven't done a ton in photochemistry, but I did all the academic work on it, and my expertise is in organic mechanisms.
You'll forgive my skepticism.

This is a nice unit that's used in doctor's offices:

Hope these help. I enjoyed the bit of research!


KY..........

Wow, you really did a lot of research. Much appreciated!

We can even fit our newspaper. I keep it right by the door to the house (garage entrance), and that's where I toss my credit cards, wallets keys, giasses, mail, etc.

I was looking for a holiday gift for one of those folks who has absolutely everything. I think I will have to pass on the UVC device, but ty again!
