Adding UV Light to Improve Air Quality

Posted by Paul Wadsworth on Wed, Dec 22, 2010 @ 09:01 AM

The quality of air indoors is often worse than the quality of air outdoors, especially considering the amount of time we spend inside in the winter. Good ventilation and air circulation, as well as the addition of an air purification system, can have a big impact on air quality. The ultraviolet component of sunlight, which is responsible for killing microbes outside, is just as effective inside when UV light is installed as part of a purification system in your home.

UV light in an air purifier gets the ominous-sounding job of taking care of “pollutant destruction.” Air purifiers use filtration and pollutant destruction to clean indoor air. The filtration part is just what it says: a filter catches airborne particles, such as dust, mold spores, and other debris. But once those irritants have been trapped in a filter, a good air purification system has a way to kill off a lot of what is caught in the filter. UV light, when added to this system, kills microbes so that they don’t continue to be circulated through your house.

UV light air purifiers use UV lamps to generate UV radiation that kills harmful microbes. In addition to being in the purifier itself, UV lamps can also be placed in the ductwork to clean the air as it circulates through. UV purification varies in effectiveness, depending on the concentration of UV light offered by the unit.

Now commonplace at hospitals and large office buildings, UV light air purifiers have been found effective and safe to use in homes.  and their use is recommended by the Centers for Disease Control and Prevention. Residential ultraviolet units use the “C” band and have proven effective in getting rid of system mold. The lights provide a nice side benefit of eliminating previously hidden odors in the house.
