The lights are placed within the ductwork or air handler of HVAC systems where nearly all the air in your home passes over it. UV light is hazardous to eyesight and they’re out of sight inside the HVAC equipment.
How UV Systems Compare
Compared to other kinds of air purification equipment, UV lighting offers:
- High energy efficiency. The new generation of UV lights use LED technology and require annual replacement. Air purifiers rely on filters that need replacement as often as semiannually that can cost much more than the UV light bulbs.
- Low maintenance. Since they’re out of sight, UV lights require little maintenance, especially if you keep the air filter for your HVAC system clean.
- Protection against VOCs. These gases are among the most common airborne pollutants in the typical home. They come from products made from hydrocarbons and have varying degrees of toxicity. The lights are the only way to reduce the VOC load in the air without relying on year-round fresh air ventilation, which isn’t realistic during the summer or winter.
- Odor-free. UV rays eliminate much of the need for disinfecting air sprays that have overpowering scents that may even include VOCs. Air sprays only offer spot protection from the spread of infectious germs, while UV lighting systems protect the whole home.
- A cleaner HVAC system. The lights will eliminate mold growth inside the air handler and the ductwork. When mold grows inside the air handler on the evaporator coil, cooling efficiency drops and air quality declines.
