Indoor air quality is something to keep in mind for every household. If your home doesn’t have the right air quality products, indoor air is frequently two to five times less healthy over outdoor air. But with so many 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 popular options—air purifiers and UV lights.
How Do Air Purifiers Work?
Air purifiers are used to improve indoor air quality by filtering 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 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 work slightly differently, but the goal is the same—to capture airborne particulates. However, once allergens fall to the floor, purifiers can no longer catch and remove them.
One underlying side-effect with many air purifiers is that they generate ozone. Whether in its natural form or mixed with other chemicals, ozone can be harmful to health. Breathing ozone affects lung function and intensifies 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 hurt it! Based on U.S. Environmental Protection Agency (EPA) instructions, homeowners are advised to stick to proven methods of managing indoor air pollution. These methods include phasing out or controlling pollutant sources, bolstering outdoor air ventilation and using any proven methods of air cleaning that doesn’t intensify 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 eliminates bacteria and molds. UV lamps have been used as a sterilization instrument in hospitals and food production for a very long time. When placed in your HVAC system, UV lights can greatly boost indoor air quality.
The process is quite straightforward: an ultraviolet lamp is installed in your ductwork, where it runs constantly. Any time the air conditioner or furnace turns on, indoor air containing particulates drifts through the light. Airborne microorganisms are deactivated after just 10 seconds of contact, rendering them unable to reproduce until they die quickly after UVC exposure. It is advised that UV lights be installed in conjunction with both high efficiency filtration and ventilation devices. All three work with one another to produce the best, most pure indoor air for your home.
Air Purifiers vs. UV Lights – Which is Recommended?
D.A. Bennett Service Experts suggest installing UV lights for maximum indoor air quality. This solution can provide relief to those dealing with asthma and allergies, especially in sunny, humid settings 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 generating ozone
If you feel a UV germicidal light is beneficial for your home, discuss it with one of our indoor air quality specialists 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 dust, pollen and pet dander since UV lights don’t affect non-living allergens.
