The most recent worldwide pandemic has increased awareness that indoor air pollutants adversely affect human health, no matter how low their concentrations are. This is because the duration of exposure to these pollutants increases during the time people live their normal day-to-day lives indoors.

Improving indoor air environments through air purification leads to positive health effects. Breathing clean air can lessen the possibility of diseases from stroke, heart disease, lung cancer, and chronic and acute respiratory illnesses such as asthma. Lower levels of air pollution are better for heart and respiratory health, both long and short-term.
