UV (ultraviolet) lights have been used for decades to clean food, water, and air in food-processing plants, hospitals, water treatment facilities, colleges, and commercial buildings.
To improve indoor air quality in homes, UV technology is also available.
A UV light system emits low levels of ultraviolet radiation to kill germs, mold, bacteria, and viruses. Microorganisms can no longer reproduce as a result of UV systems altering their cell structure. Indoor air is often sealed up to save energy which becomes a breeding ground for harmful contaminants, whereas outdoor air is cleaned by the sun and vegetation. Keeping your home’s indoor air clean is essential if you want to breathe healthy air. Air ducts are fitted with one to three UV light bulbs, and UV lights should be located near the evaporator coil as a large amount of condensate is produced by the evaporator. Mold, bacteria, and other microorganisms thrive in the moisture and darkness. Install one UV light inside the A-frame evaporator and several bulbs on its exterior tubing for best results. The lights cleans the air as it flows through the tubing. UV light systems also prevent odors and recontamination of living spaces by protecting supply ducts from contamination. It only takes a few hours to install! Since the lights are completely concealed inside the air ducts, people and pets won’t be harmed by them. The bulbs can be changed every 3 to 4 years while doing heating and A/C preventive service.
