HEPA Filters Lower Blood Pressure in High-Pollution Areas: Study
Researchers have found in a new randomized trial that using high-efficiency particulate arrestance (HEPA) filters in homes significantly reduced elevated blood pressure in individuals exposed to air pollution near major highways. However, no benefit was observed in people with normal systolic blood pressure (≤120 mm Hg). Researchers recommend targeting HEPA filtration for vulnerable populations residing […]
