What is PM2.5? How do I manage fine dust?

PM2.5, or fine dust, are fine particles that measure about 1/10 the width of a strand of hair. It’s not only invisible to the naked eye but is dangerous to our health as it is absorbed into our bloodstream and can cause or exacerbate health problems.

Sources of fine particles can come from vehicle and industrial emissions, but also from inside our homes. Cooking, burning candles, using the fireplace, and smoking are common sources of indoor air pollution. Ultrasonic purifiers that use untreated tap water can also release fine particles.
