Indoor air quality is something to keep in mind for every household. If you lack the right air quality products, indoor air is likely to be two to five times less healthy than outdoor air. But with different air cleaning methods on the market, how do you know which one is best for your home and family? Here’s a comparison of two quality options—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 capture odor-causing molecules for a pleasant scent. Air purifiers come in a portable form, which means they can only clean the air in one room at a time.
There are different types of air purifiers, including mechanical filters, activated carbon filters, ozone generators, electronic air purifiers, and ionization systems. They all work a little differently, but the goal is the same—to capture airborne substances. However, once allergens settle to the floor, purifiers can no longer trap and remove them.
One underlying byproduct with many air purifiers is that they create ozone. Whether in its pure form or combined with other chemicals, ozone can be harmful to health. Breathing ozone affects 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 use an air purifier to improve indoor air quality, not hurt it! Based on U.S. Environmental Protection Agency (EPA) guidance, homeowners are encouraged to take advantage of proven approaches of controlling indoor air pollution. These methods include phasing out or controlling pollutant sources, increasing outdoor air ventilation and using any proven methods of air cleaning that doesn’t intensify 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 called 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 drastically improve indoor air quality.
The process is quite uncomplicated: an ultraviolet lamp is installed in your air ducts, where it runs throughout the day. Each time the air conditioner or furnace turns on, indoor air containing pollutants drifts near the light. Airborne microorganisms are made sterile after just 10 seconds of contact, rendering them unable to reproduce until they die quickly after UVC exposure. It is suggested that UV lights be installed in addition to 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 Recommended?
Service Experts Heating & Air Conditioning encourages you to consider installing UV lights for the highest possible indoor air quality. This solution can bring relief to those dealing with asthma and allergies, namely in sunny, humid regions where microorganisms flourish. Unlike air purifiers, UV lights can:
- Filter the air in your entire home
- Destroy the majority of viruses, bacteria and mold
- Extend your HVAC system’s lifespan
- Reduce the possibility of creating ozone
If you believe a UV germicidal light is best for your home, talk with one of our indoor air quality Experts today. We can recommend the perfect combination of products based on your HVAC equipment and indoor air quality needs. Don’t forget, you should still use an HVAC air filtration system to remove dust, pollen and pet dander since UV lights can’t affect non-living allergens.
