Understanding PM1, PM2.5, and PM10: Health Impacts and How to Reduce Exposure Indoors

Understanding PM1, PM2.5, and PM10: Health Impacts and How to Reduce Exposure Indoors  What Are PM1, PM2.5, and PM10? PM stands for „particulate matter”—tiny solid or liquid particles suspended in the air. These particles vary in size, which determines how deeply they can penetrate the respiratory system. - „PM10”: particles with diameters ≤ 10 µm. They can reach the upper and middle airways but are largely filtered before reaching the lungs. - „PM2.5”: fine particles ≤ 2.5 µm. They can pen...
