HEPA Purifiers Cut Air Pollution Risk

by Berkeley Wellness  

If you live in an area where outdoor air pollution is often high, using an indoor HEPA (high-efficiency particulate air) purifier may reduce the health risks, suggests a Chinese study in the journal Circulation.

The study tested the air purifiers in dormitory rooms in Shanghai and found that they lowered indoor exposure to fine particulate matter by 80 percent and also reduced its adverse effects on students in the rooms (on blood pressure, stress hormones, oxidative stress, insulin resistance, and inflammation).

Fine particulate air pollution—produced by motor vehicles, power plants, factories, smoking, and forest fires—is a leading global contributor to cardiovascular disease, cancer, and lung disease.
