Our latest post in the serial about good indoor air is about particulate matter. These are fine dust particles in the air that vary from 10, 2.5 and 1 microns or even less in width. To put it in context, there are about 10,000 microns in a cm. Outdoor particles primarily come from cars, trucks, and other vehicles, while indoor particles come from tobacco smoke, cooking, burning candles, etc. These are everywhere especially on things with fabrics. Dust levels above 100 microns/m3 may cause negative short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. By using ventilation filters a majority of the particles from outside can be removed. To get rid of particulate matter already in place, consider buying an air purifier with HEPA filters.
