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

Indoor air quality is important for every household. Without the right air quality products, indoor air is likely to be two to five times more contaminated compared to outdoor air. But with so many air cleaning methods available, how do you determine which one is ideal for your home and family? Here’s a comparison of two popular options—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 collect odor-causing molecules for a pleasant scent. Air purifiers can be found in a portable form, which means they can only clean the air in one room at a time.

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

One common problem with many air purifiers is that they generate ozone. Whether in its pure form or blended with other chemicals, ozone can be detrimental to health. Breathing ozone decreases lung function and intensifies 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 weaken it! Based on U.S. Environmental Protection Agency (EPA) recommendations, homeowners are encouraged to stick to proven systems of controlling 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 called germicidal because it inactivates most viruses and wipes out bacteria and molds. UV lamps have been used as a sterilization method in hospitals and food production for a very long time. When installed in your HVAC system, UV lights can drastically enhance indoor air quality.

The process is surprisingly straightforward: an ultraviolet lamp is installed in your ventilation system, where it runs throughout the day. Any time the air conditioner or furnace starts, indoor air containing pollutants moves through the light. Airborne microorganisms are deactivated after just 10 seconds of contact, rendering them unable to reproduce until they die soon after UVC exposure. It is recommended that UV lights be used in conjunction with both high efficiency filtration and ventilation systems. All three work in unison to give you the best, most pure indoor air for your home.

Air Purifiers vs. UV Lights – Which is Recommended?

Winnipeg Supply Service Experts recommends installing UV lights for the highest possible indoor air quality. This solution can bring relief to anyone dealing with asthma and allergies, namely in warm, humid climates where microorganisms flourish. Unlike air purifiers, UV lights can:

    • Clean the air in your entire home
    • Destroy the bulk of viruses, bacteria and mold
    • Lengthen your HVAC system’s lifespan
    • Avoid the potential of creating ozone

If you believe a UV germicidal light is beneficial for your home, talk with one of our indoor air quality technicians today. We can point you to the best combination of equipment based on your HVAC equipment and indoor air quality needs. Remember, you should still have an HVAC air filtration system to trap dust, pollen and pet dander since UV lights can’t affect inanimate allergens.
