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

Indoor air quality is something to keep in mind for every home. If your home doesn’t have the right air quality products, indoor air is likely to be two to five times more polluted compared to outdoor air. But with different air cleaning methods on the market, how do you determine which one is right for your home and family? Here’s a comparison of two popular methods—air purifiers and UV lights. 

How Do Air Purifiers Work?

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

There are many types of air purifiers, like mechanical filters, activated carbon filters, ozone generators, electronic air purifiers, and ionization systems. They all perform somewhat differently, but the goal is the same—to capture airborne pollutants. However, once allergens fall to the floor, purifiers can no longer trap and remove them. 

One frequent side-effect with several air purifiers is that they generate ozone. Whether in its raw form or mixed with other chemicals, ozone can be detrimental to health. Exposure to ozone affects lung function and increases the risk of throat irritation, coughing, chest pain and lung inflammation. This is an ironic side effect, because 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) instructions, homeowners are reminded to rely on proven ways of reducing indoor air pollution. These methods include eliminating or controlling pollutant sources, bolstering outdoor air ventilation and using any proven methods of air cleaning that doesn’t intensify or create 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 considered germicidal because it inactivates most viruses and eliminates bacteria and molds. UV lamps have been used as a sterilization mechanism in hospitals and food production for a very long time. When added to your HVAC system, UV lights can dramatically improve indoor air quality. 

The process is surprisingly simple: an ultraviolet lamp is installed in your ductwork, where it runs throughout the day. Every time the air conditioner or furnace turns on, indoor air containing particles drifts near the light. Airborne microorganisms are inactivated in under 10 seconds of contact, rendering them unable to reproduce until they die shortly after UVC exposure. It is suggested that UV lights be used in conjunction with both high efficiency filtration and ventilation accessories. All three work with one another to give you the best, most pure indoor air for your home. 

Air Purifiers vs. UV Lights – Which is Best?

Service Experts Heating, Air Conditioning & Plumbing encourages you to consider installing UV lights for maximum indoor air quality. This solution can offer relief to anyone suffering from asthma and allergies, namely in warm, humid climates where microorganisms thrive. Unlike air purifiers, UV lights can: 

  • Clean the air in your entire home 
  • Eradicate the bulk of viruses, bacteria and mold 
  • Lengthen your HVAC system’s lifespan 
  • Minimize the possibility of generating ozone 

If you believe a UV germicidal light is beneficial for your home, discuss it with one of our indoor air quality Experts today. We can suggest the perfect combination of systems based on your HVAC equipment and indoor air quality needs. Keep in mind, you should still use an HVAC air filtration system to dust, pollen and pet dander since UV lights don’t affect inorganic allergens.
