Need suggestion for UV santizing wand?

Help!

These are pretty much useless for sanitation.

Can you explain a bit about this further? For example, I found out all of the Verilux UV wands have been sold out and that people are price gouging on the wands on eBay. I also found out that many of the off-brand UV wands are fake or underpowered. So may be it is useless because there are too many fake products?

For UV sanitizing, the surface has to be exposed to uv for 15 minutes to have any sort of sanitizing effect. It’s not like you can just wave a wand over an area and it’s instantly sanitized.. it doesn’t work like that.

Two questions you need to answer.
(1) do UV-C wands work to disinfect and kill specifically virus, and
(2) Just as important, are they safe to use?


Answer to (1), while industrial and hospital grade UV-C devices used to sterlize surgical equipment work, consumer UV-C wands are not as effective. They may work depending on the surface (e.g. porous, or hard), but not assured to work. Clearly do not work well on porous or uneven surfaces:

Answer to (2) IMO is clear. I would not use a UV-C wand. While they have safety features (and the manufactures claim they are safe), UV-C destroys the DNA (or RNA) code. What happens if you accidentally expose your skin or eyes to it?

From article below; "UV-C is really nasty stuff -- you shouldn't be exposed to it. It can take hours to get sunburn from UV-B, but with UV-C it takes seconds. If your eyes are exposed... you know the gritty feeling you get if you look at the sun? It's like that times 10"
You are better off cleaning with soap and detergent.

Doctor in the wkyc link (2nd link) said something similar. First he says these consumer products are not that great. and second he says "safety issues outweigh worries about germs because UV lights can be dangerous".
