The Role of UV Lights in Improving Indoor Air Quality
For fresher, cleaner air in your home, an ultraviolet (UV) lamp is an excellent choice. These professionally installed indoor air quality (IAQ) products use the same technology commonly found in hospitals. They’re becoming increasingly popular in homes as a highly effective, low-maintenance way to reduce airborne contaminants, including bacteria, viruses, and mold spores.
How Do UV Lamps for HVAC Work?
UV lamps for HVAC systems are typically installed by an HVAC technician within the indoor unit of the system, usually in the ductwork close to the evaporator coil.
The evaporator coil is a component that absorbs heat in the air that passes over it before it’s distributed through the ductwork in your home. Meanwhile, the UV light emits germicidal UVC wavelengths that prevent pathogens from replicating, reducing the concentration of mold, bacteria, and viruses in the air as it circulates through your home.
UV lamps do not use any chemicals nor need frequent maintenance, though we recommend replacing the bulb every 1 to 2 years for maximum effectiveness against indoor air contaminants.
UV Lights for HVAC Offer The Following Benefits
- May reduce the spread of disease
- Reduce airborne mold spores
- Reduce odor-causing bacteria
Do I Still Need Air Filters With A UV Light?
Yes. While UV lamps neutralize pathogens that build up on the evaporator coil, filtration is still needed to trap and remove other common indoor air pollutants like dust, dander, and pollen. You can use air purification systems and other IAQ products like dehumidifiers and humidifiers to manage allergy symptoms and help reduce the spread of disease-causing bacteria and viruses.
And while UV lights help neutralize airborne mold spores, it is essential to treat any areas of your home that harbor excessive moisture, which can create a breeding ground for mold and mildew.
