For those concerned with indoor air quality problems, air cleaning technology is often the way to go. One type of air cleaner or purifier that some homeowners find helpful is ultraviolet germicidal irradiation, or UVGI, or known more simply as UV lights.
UVGI utilizes the ultraviolet length of the light spectrum to kill germs in water and air, usually in clinical or industrial settings. But the technology has also been adapted for the home. Here’s how it works.
How Ultraviolet Lights Sterilize
Ultraviolet lights kill living organisms by interfering with the organism’s DNA so that it cannot reproduce. UV light can destroy mold spores, fungus, bacteria and viruses.
Strong UV light bulbs are installed in the HVAC ductwork and near the evaporator coils, where dampness often occurs and mold and mildew can grow. As the home’s return air is drawn into the system, the lights are focused on the coil and duct entrance, killing pollutants as they pass by.
Why You Might Need UV Technology
Ultraviolet lights are most often installed in homes that have a problem with too much moisture. Excess humidity can sometimes overwhelm the HVAC’s system’s ability to dehumidify the air, leading to damp conditions in the home and inside the system. Dampness encourages mold, which reproduces by spores. The spores may enter the home’s supply air and be redistributed in the home through the ductwork.
It’s important to first address the reasons for excess dampness in the home, such as leaking plumbing, leaks in the roof and flooding in the basement. Such moisture issues can cause a damp, moldy smell, as well as unhealthful indoor air quality that can aggravate allergies and cause other respiratory problems.
Installing UV lights in your HVAC system can help reduce your exposure to the bioaerosols, or airborne living pollutants, found in your home’s air.
UV Light Maintenance
Ultraviolet lights should be kept clean, and should also be changed yearly to ensure they are operating at full strength.
