💨 Cleaner Air, Healthier Hearts! 🫀

A new JACC randomized crossover trial shows that in-home HEPA filtration near high-traffic roads can lower systolic blood pressure by ~3 mm Hg in people with elevated baseline BP—even in areas with low PM₂.₅ levels.

🔍 Why it matters: Small BP reductions at the population level translate into meaningful drops in heart attack and stroke risk. The study also highlights the Wilder Principle—those starting with higher BP benefit the most.

🛡️ Takeaway: HEPA air purifiers are a low-risk, potentially impactful tool for cardiovascular prevention, especially for vulnerable groups living close to busy roads.
