UV lights are an effective means for improving indoor air quality



Fact
Indoor air is always 3 to 5 times more polluted than outside air.

WHY
Homes today are built to a much higher standard. Sealed tighter for better energy efficiency. But now You're Trapped Inside Breathing the recirculated Who Knows What's in the air. The tighter your home is, the more important indoor air quality is.


Benefits

HVAC UV lights:
• Control mold and bacteria
• Reduce colds and flus – germs are not re-circulated by HVAC system
• Reduce smells / odors
• Remove VOCs
• Are more effective in humid climates than dry climates
• Reduces clogging in condensate drain lines by preventing algae growth.
• Maintains a cleaner coil, improving cooling efficiency and reducing electricity costs.





In 1903, Niels Finsen won the Nobel Prize in Medicine for his use of ultraviolet light in the treatment of tuberculosis. Since then, ultraviolet lights have been widely adapted for all kinds of uses: sterilizing hospitals, sterilizing water, germicidal lamps in food establishments, and even curing nail polish faster.

UV light is so effective, it can be applied to improving indoor air quality for residential HVAC systems.
They will kill mold and bacteria in HVAC systems. We do need to understand the priorities of indoor air quality and the types of UV lights available for residential HVAC systems.

Two types of UV lights are made for sanitizing your heating and air conditioning system. They have various names including purifying lights, germicidal lights, sanitizing lights and sterilization lights.


Air Sanitizing Lights:
This type of HVAC germicidal lights are installed in the ductwork bringing return air to the system. Their purpose is to kill airborne germs and mold. Stick and U-shaped lamps are used by various manufacturers.
Some air germicidal HVAC lights are coordinated with the blower motor to turn on and off as it does. These must be hardwired with the system, so installation cost is on the high end of the spectrum.

Coil Sanitizing Lights:
If you have central air conditioning, then you have an indoor coil. It is a prime location for the development of mold and bacteria. Why?
Because the coil is used to condense moisture from the air to dehumidify your home during AC cycles. As air passes over the coil, dirt, pet dander and other debris stick to its wet surface. The combination creates an ideal setting for the growth of mold and bacteria that can be spread through your home in the passing air.
Coil UV lights are the most common HVAC sterilizing lights. Single-lamp and dual-lamp models are produced. Coil sterilization lights are installed where they can shine directly onto the surface of the coil, and they are left on continuously.
