UV-C Lights

UV-C Lights for sterilization of room air

I’ve been using UV-C lights to clean the air in my house for about two years. UV-C is ultraviolet light around a wavelength of 260 nm. This wavelength light disrupts DNA and kills mold, viruses, bacteria, mites and other unwelcome invaders.

UV at higher wavelengths ( A and B) does things like cause ozone production from oxygen in the air, or cause tanning of your skin. UV-C is carcinogenic and causes skin cancer, so you want to avoid personal exposure to the light.

About the time I first became involved in this, there were vendors falsely advertising lights that didn’t produce UV-C, so in buying lights, it’s good to test for UV-C with test strips or a meter.
