There are 3 types of air cleaner that eliminates pollutants ultraviolet germicidal irradiation (UVGI) cleaners, ozone generators and photocatalytic oxidation (PCO) cleaners. UVGI cleaners use UV lamps to destroy viruses, bacteria, allergens and molds. UVGI works well with filtration system. Ozone uses UV light or an electrical charge to produce ozone. Ozone is a lung irritant that can cause adverse health effects as reported by www.epa.gov. It is not always safe and effective in controlling indoor air pollutants.
