UV Lights in Clarksville, IN, Jeffersonville, IN, Louisville, KY and the Metro Region
UV (ultraviolet) lights have been around for some time but really got a boost in popularity after the anthrax scares started because the same type of irradiation technology is used. A UV light assembly is a bulb (or bulbs) placed in the return air stream to irradiate the air flow. This type of technology is used to kill germs and bacteria, and, is generally very effective. It is not extremely expensive to install, however there are regular maintenance costs (replacing the bulbs, usually every two years) that can be somewhat pricey.
Generally speaking this added level of air treatment is not really needed if you are using a good filter system. This is not to say that there is no segment of the population that would benefit from a UV light system, such as extreme allergy sufferers or persons with compromised immune systems. For such people a UV light system could prove extremely beneficial.
