HEPA filters reduce cardiovascular health risks associated with air pollution, study finds

Using inexpensive air filters may help reduce cardiovascular disease risk that results from exposure to air pollution, according to researchers from Canada, who studied healthy adults living in a small community in British Columbia where wood burning stoves are the main sources of pollution. The researchers found that high-efficiency particle air (HEPA) filters reduced the amount of airborne particulate matter, resulting in improved blood vessel health and reductions in blood markers that are associated with an increased risk of cardiovascular disease.
