Air Purifiers vs. UV Lights: What’s Right for My Needs? 

Indoor air quality is important for every household. If you lack adequate air quality products, indoor air is frequently two to five times more contaminated compared to outdoor air. But with a large number of air cleaning methods to choose from, how do you recognize which one is best for your home and family? Here’s a comparison of two quality choices—air purifiers and UV lights. 

How Do Air Purifiers Work?

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

There are several types of air purifiers, such as mechanical filters, activated carbon filters, ozone generators, electronic air purifiers, and ionization systems. They all perform slightly differently, but the goal is the same—to capture airborne particulates. However, once allergens settle to the floor, purifiers can no longer trap and remove them. 

One consistent problem with a number of air purifiers is that they generate ozone. Whether in its pure form or combined with other chemicals, ozone can be detrimental to health. Being exposed to ozone decreases lung function and escalates the risk of throat irritation, coughing, chest pain and lung inflammation. This is an ironic side effect, since a homeowner would only purchase an air purifier to improve indoor air quality, not hurt it! Based on U.S. Environmental Protection Agency (EPA) recommendations, homeowners are encouraged to rely on proven techniques of managing indoor air pollution. These methods include removing or controlling pollutant sources, increasing outdoor air ventilation and using any proven methods of air cleaning that doesn’t add or produce 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 called germicidal because it inactivates most viruses and wipes out bacteria and molds. UV lamps have been used as a sterilization system in hospitals and food production for a very long time. When added to your HVAC system, UV lights can dramatically boost indoor air quality. 

The process is surprisingly straightforward: an ultraviolet lamp is installed in your air ducts, where it runs throughout the day. Any time the air conditioner or furnace starts, indoor air containing particulates moves past the light. Airborne microorganisms are inactivated within 10 seconds of contact, rendering them unable to reproduce until they die soon after UVC exposure. It is recommended that UV lights be utilized in addition to both high efficiency filtration and ventilation equipment. All three work in tandem to give you the best, most pure indoor air for your home. 

Air Purifiers vs. UV Lights – Which is Recommended?

Service Experts Heating, Air Conditioning & Plumbing suggest installing UV lights for the highest possible indoor air quality. This solution can provide relief to people suffering from asthma and allergies, especially in hot, humid regions where microorganisms are in abundance. Unlike air purifiers, UV lights can: 

  • Improve the air in your entire home 
  • Eliminate most viruses, bacteria and mold 
  • Lengthen your HVAC system’s lifespan 
  • Avoid the likelihood of producing ozone 

If you believe a UV germicidal light is right for your home, talk with one of our indoor air quality specialists today. We can walk you through the ideal combination of systems based on your HVAC equipment and indoor air quality needs. Don’t forget, you should still install an HVAC air filtration system to trap dust, pollen and pet dander since UV lights don’t affect non-living allergens.
