Indoor air pollution levels are often 70 X higher than the air outdoors.
Aqua Ultraviolet air sterilizers eliminate what even the best HEPA filters can not. Installed on any heating or air duct UV will reduce air borne mold, viruses, bacteria, fungus, pollens, spores and dust mites along with odors from pets, smoke and mold/mildew. Newer homes are constructed to be more air tight increasing the need to remove VOC's, volatile organic chemicals, which become airborne at room temperature.
An average family spends more than 60% of their time indoors where these contaminants are trapped. HEPA filters in the duct work and room filters aren’t effective in reducing single celled organisms most of which are smaller than .3 microns.
