The whole idea of air cleaning is to remove particles, germs and gases which include chemicals. Many disinfectant and deodorizing sprays add unwanted chemicals to the air that can aggravate allergies and cause other ailments. Also, disinfectant sprays can only kill germs that the chemical has contact with, so you would need a lot of spray to disinfect all of the air in your home. A powerful Elevated Air dual wavelength UVC/UVV light installed into your ducts will disinfect and deodorize your indoor air 24 hours a day naturally without using chemicals or sprays.
