Encouraged by articles showing that doing your laundry didn’t tend to kill all bacteria and also those stories of people freezing their jeans to cull bacteria, I started researching UV-C, the spectrum of UV light that doesn’t come into our atmosphere, and seemingly will kill most things pretty rapidly on contact.
Safety: Is key. this light will cause retinal damage in a matter of seconds and it’s not great for your skin. These reasons also mean you should avoid it with pets. You can wear protective eyewear, but more than likely some of your skin will contact the light depending on your bulb. Another aspect is that it quickly degrades plastics.
The most hyped application is using this in your HVAC air handler to reduce mold buildup on your AC coils and potentially in your ducting. It is anti viral, anti bacteria, anti fungal, and anti plastic… but much of this is determined by duration; so air that is rapidly flowing past the light may not be as sanitized as still air. (though all of the surfaces immediately in contact with the light are).
A new concept that I was also intrigued by, was portable washing machines (such as RV use) these use less water and are perhaps more “innovative” or at least gimmicky. But, you can also add a UV light to the lid of a traditional (basin) washer easily. And the gyration should expose most surfaces to the light on top, but especially in light loads.
Finally, personal use. Which, I hope has made my pandemic life easier (if only because I bought this wand in late 2019 because my girlfriend travels with work and a peace of mind over bedding could be nice?) But this is a little AA powered wand with a UV-C bulb in it, and also with a float switch so that it makes it particularly difficult to shine in your own eyes. But, with a pandemic, and UV-C able to kill RNA viruses rather rapidly, I get some peace of mind by scanning common surfaces or light contact points quickly with it; a slow scan “may” be affective?
