Clean Indoor Air: Breathe Easier

By Randy Arthur

President, Arthur Air Conditioning

Ultraviolet light attachments inside the air handler of your A/C system can provide a healthier
atmosphere for your family, especially at this time of year, when homes tend to be closed up and air
is recirculating inside. The more tightly sealed your  windows and doors, the less fresh air moves
into your home, and the more important it is to make sure recirculating air is as clean as possible.   

Take some common-sense precautions to keep your indoor air quality as good as possible before
investing in any equipment:

  • Limit indoor tobacco use

  • Don’t burn candles

  • Don’t idle your car in an attached garage

  • Run the exhaust fan over the stove while cooking


These won’t keep all pollutants out of your indoor air. Especially here in Florida, it seems allergy
season is nearly year ‘round. Ultraviolet (UV) lighting installed inside your air handler will kill at least
some of the mold spores (like the one pictured below,) mildew, bacteria and viruses that are silently
floating in your house.

Ultraviolet Germicidal Irradiation has been used for airborne and surface disinfection since 1909
when Marseilles, France, used it to disinfect the city’s water supply. Previously limited to hospitals
and municipal water treatment plants, UV light has come into household use at its price has come
down. It works by breaking apart the molecular bonds of the DNA of microorganisms so they cannot
reproduce.  Spores and some types of bacteria take more time to break down; other invaders are
easy targets.   

UV lights do not take the place of clean filters! Changing your filters precisely on time is just as
important, because filters remove particles that UV cannot touch. For the cleanest indoor air
possible, use both ultraviolet light directly on recirculating air and a fresh filter.
