What Is a UV Air Treatment?


When it comes to safeguarding the health of your family at home or your employees at work, keeping the air clean and free of airborne allergens and microorganisms should be one of your top priorities.

For many homeowners as well as business owners, the prospect of bacteria, microbial growth, allergies and unwanted odors is enough to prompt them to consider getting ultraviolet (UV) light air treatment to work with the heating, ventilation, and air conditioning (HVAC) equipment.

While it's a good start to use air filters in your heating and air conditioning equipment, even the best filters cannot purify the air the way UV air treatment can. The most efficient filters have holes that are too large to let them trap smoke and other indoor pollutants, pet odors and unwanted things such as microbial growth, bacteria and viruses.

You should know that the experts at David Gray Heating & Air are well trained in helping customers evaluate their systems and determine the best type of UV air treatment to use in their home or place of work.

Reasons for Using UV Air Treatment

Anyone who has suffered from allergies or has coworkers or family members who are prone to allergies from airborne materials will definitely want to consider using UV air treatment to reduce or eliminate the problem.

If your building is prone to microbial growth, you should be aware that UV air treatment is extremely effective in eliminating up to as much as 99.9 percent of all the microbial growth in your HVAC system.

Companies that install UV air treatment equipment can expect to see fewer employees having to take sick days because of illnesses such as allergies. Doing so will make your office run more efficiently, save you money and help you surpass your competitors.

Families that add UV air treatment to their home HVAC systems typically will see that their children have less sick days that keep them out of school, with the whole family generally enjoying better overall health.

How it Works

A UV light emits ultraviolet light rays, which are invisible to people but have the power to sterilize your air conditioning equipment. In nature, sunlight serves to kill microbial growth and floating bacteria in the air, but inside your home, even when you have your windows open to admit sunlight, it's possible for mold and microorganisms to survive and even thrive on your HVAC equipment.

The UV light will destroy microbial growth and mildew as well as unhealthy microorganisms. Ultraviolet light works to kill germs as well as destroy harmful pollutants.

With optional odor-reducing equipment, your UV air treatment system can help get rid of annoying smells, giving you a fresher environment for coworkers, family and friends.


UV air treatment will reduce most microbial growth from your system, as well as killing the majority of airborne bacteria.

Besides helping keep everyone on the premises safer and healthier, the UV air treatment will also let your HVAC system run more efficiently. By removing the buildup of microbial growth and other debris on your AC coil, your system works better at keeping the building cold.

What's more, you stand to save on maintenance and cleaning charges, because the UV treatment means you won't have to have the coils cleaned as often.

Fresh air is crucial for maintaining the health of your employees at your place of work as well as your family and friends at home. It is particularly important to ensure clean air at home when you have young children who are prone to illness, have anyone in the building who has a chronic disease, as well as elderly people in general and anyone who suffers from allergies.
