Reduce Indoor Allergens this Fall with UV Lights

Fall allergies are not funny. The most effective way to reduce allergens in your home is simply to remove as many of the allergens as possible.

If you have tried to reduce indoor allergens before, you know that it is a task easier said than done. When properly maintained, your HVAC system filters are effective up to a point. However, even the premium filter lets a large number of allergens and pollutants through to recycle in your air.

Does that mean you’re doomed to a contaminated home that affects your air quality? Thankfully, the answer is no. There is a solution available that’s been around for a while but most homeowners aren’t aware of: ultraviolet (UV) lights.

How UV Lights Work

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

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

Are UV Lights Safe?

Some homeowners may be concerned over the safety of ultraviolet lights. While UV rays from the sun can be damaging, UV air cleaners are installed within ductwork where they don’t come in contact with people. UV lights also don’t use chemicals or produce ozone, so they’re a safe method for removing indoor allergens.

A Two-Pronged Attack

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