What Does a UV Air Purifier Do?

Indoor air quality is important: it helps with comfort and the health of your family. But not all air cleaners do the same thing, especially when it comes to biological pollutants. Some air cleaners with higher MERV ratings can capture biological pollutants that are larger in size, but to truly eradicate microbes like bacteria, viruses and mold and mildew spores, you’ll want to look at how a UV air purifier in Port Aransas can help you.

What Is a UV Air Purifier?

A UV air purifier, also known as UV germicidal lighting or UV lights, is an air purifier that destroys the DNA of biological pollutants, rendering them incapable of reproducing or sustaining life. A UV air purifier accomplishes this by using the radiation from UV-C light rays.

Where Is It Installed?

Placement is flexible, but a common spot is the evaporator unit in your air conditioning system, typically over the coils. This helps keep your coils free from developing growths like mold and algae while also purifying the air that passes under the lighting.

Will a UV Air Purifier Remove Dust and Dirt?

A UV purifier is not a filter; as such, it does not capture and collect dust and dirt. If you are concerned about dust and dirt, it is recommended that you pair UV lighting with an air filter.

How Often Does a UV Air Purifier Operate?

Unlike air filters that only capture particles when your system is in operation, UV lighting operates 24/7. The amount of electricity they use is small, about 7 cents per day.

What Are Some Other Benefits of UV Lighting?

  • Over 99% effectiveness in killing biological pollutants
  • Flexible placement, including in vents and over the coils of your system
  • Helps with your air conditioner’s energy efficiency by killing off mold and other biological debris that can affect the operation of your system


UV lighting is relatively easy to maintain. The most important step is to make sure the light bulbs don’t become covered with dust; if they do, clean them off to maximize their continued performance. Secondly, UV lights last about a year, so it’s recommended the lights are changed annually, even if your current ones are still working.
