There is more than one way to purify the air in your home! This UV light technique for your HVAC system uses a germicidal light that produce UV wavelengths, strong enough to kill even the smallest bacteria. Although this method of air cleaning may seem low maintenance, there are several specific requirements that occasionally need to be addressed. Could this be the right air filtration for your home? Before you decide on this air purifying system, check out these pros and cons that will help determine your decision.

Energy Efficiency

UV filtration systems can be placed above an air conditioning unit to catch any micro-organism that may pass through the system. The AC unit can run smoothly and efficiently while the UV filter captures mold and dust from gathering around AC unit and eventually causing build-up. This is a helpful way for an AC to work properly; however, you should pay attention to the surface of the UV bulb. The UV system may kill the bacteria, but it does accumulate dust and needs to be cleaned in order to function properly. Always shut off the UV purifier before performing any maintenance.

Eliminates Bacteria

Most generic filters can’t hold a candle to the eliminating power of UV purification. Over 99 percent of mold, viruses, and bacteria are destroyed by the UV ray that pass by the filter. As long as your AC unit is running at a moderate speed, the UV filter can work efficiently.

Shelf Life

UV bulbs require an annual replacement. After a while, the bulbs become dim which can interfere with their ability to filter microorganisms. Should you notice the UV light become dim or inactive, replace the bulb immediately. It may seem as though the system will be filtering the moving air, but dim UV lights are not as effective as a well-lit system. It will be expending more than necessary energy but you’re still exposed to lingering bacteria if you don’t change the bulb regularly.

Limited Usage

Without extra filters throughout the home, you are still breathing in dust that contains allergens. UV filters only disinfect the air with living bacteria, not catch the particles themselves. You will want to keep additional air filtration units close by to filter the dust, while the UV purification system does the rest of the disinfecting.

What are the types of UV Air Filtration?

Air and coil sterilization are the two types of UV filtration. Coil is most common and runs 24/7. It is installed inside the return air duct and sterilizes the air handler coil. Air UV filtration sterilizes the air that moves by. This type of filtration moves the passing air through the HVAC unit and cycles the air handler blower. Should you have questions regarding the type of filtration that will benefit your home, a local ac contractor may put your mind at ease.

The Bottom Line

In addition to your AC unit, UV filtration will benefit the quality of your air by reducing mold and allergens, eliminating odors and bacteria, and maintain a cleaner coil to provide low energy costs. Only micro-organisms that are in the sight of the UV filter are eliminated effectively, not all particles. In order to maintain the health of the UV system, you must keep a healthy HVAC unit. Check your AC unit filters and clean it when necessary. When you’re ready to put the UV filter to the test, the experts at AirTemp will guide you in the right direction.
