Understanding the importance of protecting your equipment from contaminates.

Air borne contaminates spread through out your home as your Central Air System re-circulates the air. With no disinfective protection you and your family are susceptible to bacteria, mold, allergenic, and viruses. Some of these organisms are extremely annoying while others actually make you sick! An air condition system left untreated becomes a breeding ground for all contaminates mention above eventually clogging up your system's evaporator coil, blower wheel and unit cabinet.


The part of the ultraviolet light that's kills the germs is the UV-C light. As the molecules pass through your system they get eliminated, turned into harmless carbon dioxide and water vapor. The UV light also helps reduces volatile organic compounds such as cooking smells, paint, varnishes, chemicals and tobacco smoke. Microbes exposed to Ultraviolet light are 90% eliminated after only 10 minutes of exposure, after 24 hours the UV light would have had eliminated 99.9% of all contaminants in the air you and your family breath on a daily bases.
