If you’ve been searching for an affordable way to purify your home’s air, look no further than UV lights (ultraviolet). Unlike other devices, these lights work soundlessly behind the scenes to reduce the populations of airborne bacteria, viruses and mold spores. Any home with a forced-air heating and/or cooling system can use these lights to improve air quality.
UV is a light spectrum found in sunshine and acts as nature’s disinfectant. It alters the DNA of mold spores, bacteria and viruses so that they can’t reproduce. The lights are so effective that they’ve been used for decades in institutional medical settings, hospitals, clean rooms and public buildings to reduce the spread of diseases.
Volatile organic compounds (VOCs) emit harmful gases inside homes and buildings. Their degree of toxicity varies on an individual basis, but many are known carcinogens and nervous system and respiratory irritants. UV light exposure is the only way to reduce their harmful effects, other than dilution with fresh air ventilation.
Where They’re Placed
As beneficial as UV light is, it’s harmful to eyesight without protection. When the lights are placed inside an HVAC system, they eliminate the risk to eyesight and treat all the air that passes over them.
The UV lighting can be installed inside the ductwork or aimed at the evaporator coil inside the air handler or blower compartment in HVAC systems with air conditioning. In this position, the lights prevent mold and biofilm growth on the coil, which reduces HVAC system efficiency and can lead to premature part failures in air conditioners.
HVAC systems equipped with LED UV lights use small amounts of electricity, and all types of UV systems don’t require fans or air filters to purify the air. Depending on the particulate load in your air, they need periodic dusting to maintain their full effectiveness, along with annual replacement.
Year-round, UV lights will provide fresher, cleaner air in your home with a small investment and maintenance. To learn more, contact Cool Power, LLC, providing trusted HVAC services for Long Island homeowners.
