According to the EPA, the indoor air can be 2-5 times worse than the outside air. Dust, dander, mildew, mold, allergens, bacteria, off gassing, etc. are all trapped in your home. The only way to eliminate most of these pollutants is with ventilation and filtration.
The two most effective ways to maximize your indoor air quality are with U.V. and filtration.
U.V. Light for HVAC
U.V. (Ultra Violet) has been used for years in various capacities to kill bacteria and viruses. Many municipalities use U.V. for treating drinking water. In your home, germs are distributed via your duct system. U.V. light, a natural component of sunlight, destroys many of these pathogens. A U.V. installed in your duct system will destroy any living organism within your ducts.
Filtration is what we refer to as air cleaners They come in a variety of styles and degree of effectiveness. Their primary function is to trap particles as small as in the micron level. Some of the best air cleaners have been certified to destroy viruses, like COVID-19.
