Air Purifiers vs. UV Lights: What's Best for My Home?

Indoor air quality is something to keep in mind for every homeowner. Without adequate air quality products, indoor air is likely to be two to five times more polluted than outdoor air. But with a large number of air cleaning methods to choose from, how do you know which one is ideal for your home and family? Here’s a comparison of two quality methods—air purifiers and UV lights.

How Do Air Purifiers Work?

Air purifiers are designed to enhance indoor air quality by removing dust, tobacco smoke, and pollen from the air. Some also absorb odor-causing molecules for a fresher scent. Air purifiers are available in a portable form, which means they can only work in one room at a time.

There are different types of air purifiers, including mechanical filters, activated carbon filters, ozone generators, electronic air purifiers, and ionization systems. They all work somewhat differently, but the goal is the same—to trap airborne particulates. However, once allergens drift down to the floor, purifiers can no longer capture and remove them.

One consistent side-effect with several air purifiers is that they create ozone. Whether in its raw form or mixed with other chemicals, ozone can be harmful to health. Exposure to ozone hampers lung function and escalates the risk of throat irritation, coughing, chest pain and lung inflammation. This is an ironic side effect, considering that a homeowner would only purchase an air purifier to improve indoor air quality, not make it worse! Based on U.S. Environmental Protection Agency (EPA) recommendations, homeowners are advised to rely on proven approaches of controlling indoor air pollution. These methods include phasing out or controlling pollutant sources, adding outdoor air ventilation and using any proven methods of air cleaning that doesn’t intensify or generate ozone.

How Do UV Lights Work?

Ultraviolet-C (UVC) rays are the highest energy portion of the UV radiation spectrum. This type of light is known as germicidal because it inactivates most viruses and kills bacteria and molds. UV lamps have been used as a sterilization system in hospitals and food production for many years. When placed in your HVAC system, UV lights can drastically boost indoor air quality.

The process is quite straightforward: an ultraviolet lamp is installed in your air ducts, where it runs constantly. Any time the air conditioner or furnace turns on, indoor air containing particulates moves near the light. Airborne microorganisms are made sterile within 10 seconds of contact, rendering them unable to reproduce until they die shortly after UVC exposure. It is advised that UV lights be used in conjunction with both high efficiency filtration and ventilation systems. All three work together to produce the best, most pure indoor air for your home.

Air Purifiers vs. UV Lights – Which is Better?

Pardee Service Experts encourages you to consider installing UV lights for maximum indoor air quality. This solution can bring relief to those suffering from asthma and allergies, especially in hot, humid regions where microorganisms prosper. Unlike air purifiers, UV lights can:

  • Improve the air in your entire home
  • Eradicate the majority of viruses, bacteria and mold
  • Extend your HVAC system’s lifespan
  • Prevent the potential of creating ozone

If you think a UV germicidal light is right for your home, chat with one of our indoor air quality technicians today. We can suggest the ideal combination of systems based on your HVAC equipment and indoor air quality needs. Don’t forget, you should still have an HVAC air filtration system to dust, pollen and pet dander since UV lights won't affect non-living allergens.
