Tech you didn’t know existed: UV Lights
Uv lights are being used to kill germs in hotel rooms. Have you seen a sticker stating such? Did you think to yourself, yeah right?
UV Lights for Cleaning and Disinfection
Many hotels (especially post-COVID) started using ultraviolet-C (UVC) lamps to disinfect rooms between guests.
This is in addition to their normal wiping and cleaning routines, and is supposed to kill bacteria, viruses, and mold spores by breaking down their DNA.
Where is it used? Just about everywhere — on surfaces like remote controls, bedding, doorknobs, and bathroom surfaces.
There are different types:
Handheld UV wands for spot disinfection.
Standalone UV towers or robots that sanitize entire rooms after checkout.
In case you’re wondering, UVC light is not safe for skin or eyes exposure — rooms should be unoccupied while it’s used. After all, this is similar to what we are filtering out with UV protection in sunglasses and even clothing.
