UV (ultraviolet) lights have been used for many decades to clean food, water, and air in food-processing plants, hospitals, water treatment facilities, schools, and commercial buildings.
To improve air quality in homes, UV technology is also available. A UV light unit 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 and becomes a breeding ground for harmful contaminants, whereas outdoor air is cleaned by the morning light and vegetation, but keeping your home’s indoor air scrub is essential if you want to breathe healthy air. Air ducts are fitted with one to more than five UV light bulbs, and UV lights should always be located near the evaporator coil as an immense amount of condensate is produced by the evaporator. Mold, bacteria, and other microorganisms thrive in the moisture and darkness. Install a single UV light inside the A-frame style evaporator and three bulbs on its exterior tubing for best results. The lights sterilize the airflow as it flows through the tubing and UV light systems also prevent smells and recontamination of living spaces by protecting supply ducts from contamination. It only takes a few minutes to install and since the lights are completely concealed inside the air ducts, people and pets will not be harmed by them. The bulbs can be changed every two or three years during heating, ventilation and A/C preventive service.
