This Fall Reduce Indoor Allergens with UV Lights

Fall allergies are plain no fun. Considering all the methods to reduce allergens in your home, the most effective is to remove as many of the allergens as possible.

If you have already tried to reduce indoor allergens, you know that it’s a task that’s easier said than done. When properly maintained, HVAC filters are effective up to a point. Please note that even the best filter lets a large number of allergens and pollutants through to recycle back into your home’s air.

Does it mean you’re doomed to a home full of indoor contaminants that can affect your air quality? Thankfully, the answer is no. There’s a solution that has been available for a while but many homeowners just aren’t aware of: ultraviolet (UV) lights.

How UV Lights Work

Ultraviolet lights are proven to be extremely effective against many different airborne contaminants. They are most often installed inside the ductwork of a home and operate in two ways to improve indoor air quality:

  1. Air containing various contaminants moves through your ducts to then pass the rays of UV light. The lights alter the DNA and RNA of these contaminants, weakening them so that they’re no longer able to grow or reproduce and die off quickly.
  2. In addition to disinfecting your air from outside pollutants, ultraviolet lights also may help eliminate the natural growth of mold on your HVAC coil and drain pan.

Are UV Lights Safe?

Some homeowners could be concerned about the safety of ultraviolet lights. While UV rays from the sun are proven to be damaging, UV air cleaners are installed inside ductwork where they don’t come in contact with you or your family. UV lights don’t use chemicals or produce ozone, so they’re a known safe method for removing indoor allergens.

A Two-Pronged Attack

By themselves, both UV air cleaners and properly maintained filters can assist in removing allergens from your home. Used together, they’re even more effective for getting the indoor air quality you need.
