Considering Improving Your Home’s IAQ by Using UV Lights? Here’s What to Know

Considering Improving Your Home's IAQ by Using UV Lights? Here's What to KnowYou may not spend a lot of time thinking about the quality of the air inside your home. However, clean air can help keep everyone in the home healthy. It has even greater benefits for allergy sufferers and for those with breathing difficulties. Improving your indoor air quality, or IAQ, is a fairly easy task that offers a great return on your investment.

What Affects IAQ?

The quality of your air can be affected by many factors. If you have smokers or pets in the home, if you have pollen-bearing plants in your yard or neighborhood, or if there’s a major roadway nearby, your air may not be as clean as you’d want it to be. Other factors affecting IAQ include having lots of dust in the air or high levels of humidity that might encourage mold growth.

What Improves IAQ?

The first, and simplest, fix for your IAQ is a good filter for your HVAC system. If you replace it regularly, a filter will catch many of the larger allergens and contaminants that get into your home.

Filters aren’t sufficient to catch the smallest particles, however. They also don’t do much about mold or mildew growth inside your ducts or around your A/C’s evaporator coil.

To take care of these contaminants, many homeowners opt to install UV, or ultraviolet, lights inside their ducts or near their evaporator coils. These lights work at a wavelength that attacks bacteria and mold spores. The lights disrupt the contaminants’ DNA, preventing them from reproducing and shortening their lives.

Since UV lights are installed within the HVAC system, they have no effect on the people or pets living in the home. These lights are remarkably effective. They have been shown to improve IAQ in less than an hour after being turned on, and they continue to clean the air as long as your HVAC system is on. Paired with a high-quality filter, UV lights can give you the indoor air quality your family needs to stay healthy.
