UV Lights – What’s the Glow? | Improve Your Home’s Indoor Air Quality

Improve Indoor Air Quality with UV Lights

Heating and cooling systems make homes and businesses comfortable places to live and work by controlling temperatures and humidity levels and circulating air. While this is beneficial if the air is clean, circulating contaminants can negatively affect indoor air quality. That’s why it’s important to make sure you have the right air cleaning devices installed.

A Simple Way to Improve Indoor Air Quality

One simple way to improve the air quality air in your home is to install ultraviolet lights in your HVAC system.

Improved indoor air quality can benefit your everyday life by:

  • Controlling mold and bacteria;
  • Reducing infectious diseases;
  • Reducing smells and odors;
  • And improving asthma.

How UV Lights Clean the Air

UV lights purify the air by killing mold and bacteria, ultimately funneling clean air into the HVAC system for circulation. UV lights remove contaminants by emitting a light that destroys their DNA makeup. The contaminant is then not able to repair itself and is considered non-threatening.

UV lights are not a one size fits all application. You need to consider the location and size of the HVAC system and the number of UV lights you’ll need. Consult your local HVAC contractor for help installing ultraviolet lights to breathe cleaner air.

  1. Is it the light that destroys the mold and contaminates or is the light producing a low grade toxic ozone that attaches and destroys the spore?

    • The light itself affects the DNA of the mold, fungus, or virus (microbes in general). When these pollutants come into contact with the light, the light will fuse the DNA and cause the microbes to die. This is why it is important to have a properly sized light to get the best benefit. Just having a glow from the light doesn’t get enough penetration to kill the microbes. The light itself and strength of the light is what affect the DNA. The light has to be sized correctly to provide enough penetration to kill the microbes.
      It is also important to note that people should not look or be exposed to the light directly as there are side effects associated with direct exposure.

    • UV Iights are typically installed in ductwork just above the evaporator coil. This is typically where mold can grow due to the moisture that collects on the evaporator coil.
      If your manufactured home has ductwork and a light that is sized properly, you should be able to have one installed.

    • There are light kits that you can purchase to kill mold and bacteria spores. You take the lights and hold them over the affected area for a specified time.
      However exposure to the UV light can have side effects to humans. Safety precautions should be observed.
      The lights discussed in this article are meant to be installed in the ductwork for the HVAC system to kill the mold and bacteria that is circulated through the system.
