Keep Your Home Healthy with a UV Air Purifier

As air recirculates through your HVAC system and your Birmingham, Alabama, home, it can become stale and unhealthy. Mold, mildew, dust mites, bacteria, and viruses cause allergies, upper respiratory problems, and other breathing problems. They also aggravate asthma, and they’re particularly dangerous to people with immune deficiencies or other health problems. A UV air purifier is one of the most effective ways to keep tiny organisms from lowering your indoor air quality.

How UV Air Purifiers Work

UV or ultraviolet light has shorter wavelengths than visible light. UVA and UVB light cause sunburn, but they can’t kill bacteria or other microorganisms or keep them from reproducing like the UVC light used in UV air purifiers. UVC light has the shortest wavelength, and it works by damaging the genetic structure of germs. The earth’s atmosphere filters out UVC light from the sun.

Types of UV Air Purifiers

A coil sterilization light sticks to the inside of the air handler with a strong magnet and points at the evaporator or induction coil, which carries cold refrigerant from your air conditioner. Its cold temperature often causes condensation and mold growth, especially in our humid climate. The light stays on to prevent this and extend the life of your HVAC system.

You can also install a more expensive air sterilization UV light in your return air duct to prevent germs and to increase your system’s efficiency. These lights only switch on with the air handler blower, so they use less energy.

Maintaining Your UV Air Purifier

You should replace your UV light once a year. Some models have an indicator that glows while the light is on. To keep it working efficiently, clean your UV air purifier with isopropyl alcohol once a month when you check your HVAC system’s air filter.
