This purifier uses a UV light that has electromagnetic radiation that will destroy bacteria and other pathogens by breaking the molecular bonds in their DNA. UV air filters kill these particles without any actual filtration, but rather use rays of ultraviolet light to eliminate them as they pass.
A UV light air purifier works well to kill bacteria, viruses, molds, and yeasts that may remain in the air. Unfortunately they will not take care of dust, allergens, or solids in the air. UV light can be beneficial to those who get sick often because they help prevent illness and diseases. Air purifiers with UV filters are often used in sterile environments such as hospitals, kitchens, daycares, and labs. In residential use, they are great for controlling mold.
Optimal performance is attained when these air filters are used in unison with other types of air filters. That way they can work together to remove a wider spectrum of air contaminants such as odor, chemical fumes, and allergens that UV air purifiers do not remove.
Some ultraviolet filters generate ozone to kill bacteria and sometimes may not be properly dispersed, posing a serious health concern. If purchasing an Ultraviolet light air purifier, make sure to find a system that does not produce ozone.
