UV lighting is used to sanitize the air in hospital operating rooms, a technique that has been adapted for home use. UV lights are placed in the duct system and near air conditioning coils to literally sterilize biological contaminants. They keep the air in your home free of mold spores, mildew, bacteria, dust mites and viruses. They also prevent the formation of mold and mildew on air conditioning coils, which is a common problem.
