What Types of Contaminants Do UV Germicidal Lights Target?

The quality of your air depends in large part on what flows through the ducts every day. Your heating and air conditioning system recycles air for use again and again. As you breathe in this air, you also breathe in anything that may have collected in the ductwork. While there are filters in your heating and air conditioning system to prevent this from occurring, they cannot filter out every type of particle, and your ducts may be home to other contaminants that could provoke an illness. Learn about why you should use UV lights in conjunction with your HVAC system to rid your home of bacteria and viruses, surface mold, and even foul odors.

  • Bacteria and Viruses: UV germicidal lights can actually help prevent the spread of disease by sterilizing and killing microorganisms like harmful viruses and bacteria. Ultraviolet light can damage organic material when it comes into contact with it. When people go outside in the daylight for a short period of time, it usually carries little or no effect. But for a microorganism like bacteria, UV exposure can prove fatal. UV germicidal lights eliminate bacteria which could trigger an immune disorder or viruses that make your family members ill.
  • Surface Mold: UV lights are often used specifically to target the mold that may potentially develop on the inside evaporator coil of your air conditioning system. The evaporator coil collects moisture as condensation when refrigerant moves through the coil, which is helpful to homeowners because this keeps humidity levels under control. However, excessive moisture creates ideal circumstances for mold development. As air blows over the wet coil and into your home, you and your family members breathe in the air along with any mold spores that could aggravate allergies, asthma, and other respiratory conditions.
  • Odors from Cooking or Pets: Finally, UV germicidal lights can sometimes get rid of lingering odors that are byproducts of cooking as well as pet odors. In fact, sewage treatment plants use commercial UV treatment technology to control odors and reduce the chances of corrosion.

A UV germicidal system may not be the best choice for every homeowner. Discuss your indoor air quality concerns with a technician to decide whether you would prefer an air cleaner or humidifier instead.
