Ultraviolet lights are commercially available, mostly for antimicrobial purposes, but new research from the University of Colorado suggests uses against allergens in homes, schools and workplaces. They discovered generally safe ultraviolet light treatment can disable airborne allergens within thirty minutes—giving people another tool to fight allergens at places where the allergens accumulate indoors. Pets, dust mites and even plants emit their own unique allergens, but unlike bacteria and viruses these allergens can’t be killed because they were never alive. UV light doesn’t remove the allergens, it renders it inactive, thus providing relief to the estimated one-in-three adults and children in this country with allergies.
