It’s worth noting, however, that not all air purification systems are created equal. Certain purifiers, known as “ozone generators”, produce the compound ozone, a highly reactive gas that serves to clean the air by latching onto molecules like mold, smoke, and other pollutants and eliminating them.
Ozone gas can be harmful to health, damaging the lungs and causing a range of different symptoms. According to the EPA, some studies show that ozone concentrations produced by ozone generators can exceed health standards even when following manufacturer’s instructions.
