Improving Indoor Air Quality with UV Germicidal Lights?
admin • April 30, 2012

To improve the indoor air quality use ultraviolet germicidal lights in Portland homes to kill harmful bacteria, viruses, and toxic mold that can cause respiratory problems and other health concerns. These microorganisms spread by releasing airborne spores containing the genetic material used to create a new organism. UV lights use a wavelength of ultraviolet light to destroy the organism’s DNA, which takes away their reproductive capabilities and also kills them.

UV germicidal lights are fairly inexpensive and can be installed to work with your existing forced air HVAC system. They are typically used in tandem with either an electronic or mechanical air cleaner. While air cleaners can filter pollen and other irritants, UV germicidal lights destroy the viruses and mold spores once these pollutants have been trapped by the air cleaner. After the air has been filtered through your HVAC, it will circulate more easily through system and increase the efficiency of the unit. In addition, UV lights are useful in killing hidden mold growth, which can only be detected by special thermal imaging equipment.

Homeowners with particularly chronic allergy problems or extremely poor indoor air quality choose to install both types of air cleaners, in addition to a UV light, for the ultimate protection from indoor air pollutants—from bacteria to pet dander.  If your home lacks adequate ventilation, or if you are unable to control the source of common pollutants, you might benefit greatly by installing UV germicidal lights. Poor indoor air circulation can exacerbate the spread of harmful microorganisms, so make sure you have proper ventilation if you don’t have UV lights in your home.

UV germicidal lights have also been used to filter tap water because they are more reliable and easier to install than other water treatment systems. However, they are typically used to provide cleaner indoor air quality.
