Air Purifiers vs. UV Lights: What’s Ideal for My Home? 

Indoor air quality is something to keep in mind for every household. If you lack the right air quality products, indoor air is frequently two to five times more polluted than outdoor air. But with so many air cleaning methods to choose from, how do you learn which one is best 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 used to improve indoor air quality by removing dust, tobacco smoke, and pollen from the air. Some also capture odor-causing molecules for a fresh scent. Air purifiers are available in a portable form, which means they can only be used in one room at a time. 

There are different types of air purifiers, such as mechanical filters, activated carbon filters, ozone generators, electronic air purifiers, and ionization systems. They all function a little 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 common side-effect with several air purifiers is that they produce ozone. Whether in its pure form or blended with other chemicals, ozone can be harmful to health. Breathing ozone weakens lung function and enhances the risk of throat irritation, coughing, chest pain and lung inflammation. This is an ironic side effect, since a homeowner would only use an air purifier to improve indoor air quality, not hurt it! Based on U.S. Environmental Protection Agency (EPA) recommendations, homeowners are reminded to rely on proven methods of reducing indoor air pollution. These methods include eliminating or controlling pollutant sources, increasing outdoor air ventilation and using any proven methods of air cleaning that doesn’t add 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 eliminates 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 dramatically increase indoor air quality. 

The process is quite simple: an ultraviolet lamp is installed in your ventilation system, where it runs constantly. Any time the air conditioner or furnace starts, indoor air containing particles blows past the light. Airborne microorganisms are inactivated after just 10 seconds of contact, rendering them unable to reproduce until they die shortly after UVC exposure. It is suggested that UV lights be used alongside both high efficiency filtration and ventilation accessories. All three work together to give you the best, most pure indoor air for your home. 

Air Purifiers vs. UV Lights – Which is Better?

Service Experts Heating, Air Conditioning & Plumbing suggest installing UV lights for enhanced indoor air quality. This solution can offer relief to anyone suffering from asthma and allergies, particularly in hot, humid climates where microorganisms are in abundance. Unlike air purifiers, UV lights can: 

  • Improve the air in your entire home 
  • Destroy the bulk of viruses, bacteria and mold 
  • Enhance your HVAC system’s lifespan 
  • Minimize the likelihood of generating ozone 

If you believe a UV germicidal light is right for your home, chat with one of our indoor air quality Experts today. We can suggest the best combination of equipment based on your HVAC equipment and indoor air quality needs. Don’t forget, you should still install an HVAC air filtration system to collect dust, pollen and pet dander since UV lights don’t affect inanimate allergens.
