According to the Environmental Protection Agency (EPA), indoor air pollution is among the top five environmental health risks we currently face. The best way to address the risk of breathing polluted indoor air is to eliminate the source of pollutants with ventilation and filtration. An air purifier can reduce the concentration of airborne pollutants and allergens in a designated area. The amount of pollutants removed by an air purifier will differ, depending on the specifications of the particular unit.

Air quality is integral to good sleep. Unfortunately, a wide assortment of contaminants-including dust mites, microbes, bacteria, viruses and volatile organic compounds (VOCs)- are commonly found in bedrooms. To cleanse their sleeping areas of contaminants, as well as unpleasant smells, many sleepers turn to air purifiers. These devices can benefit sleepers with allergies and asthma, as well. Air purifiers rid rooms of contaminants using either active purification, which converts chemicals and gases into harmless molecules; or passive purification, which extracts contaminants using a built-in filtration system.

Additionally, some models utilize two or more of these systems, as well as active purification UV technology.
