What is PM10 & PM2.5 and what does it do?

PM10 - Particulate Matter < 10µm (particles likely to be inhaled by humans). Produced by vehicle exhaust - diesels produce more. Its not good if you have asthma or breathing problems. It can irritate your eyes, nose, throat, lungs, and can effect the heart and blood hence reduce your life expectancy.

PM2.5 - Particulate Matter < 2.5µm - very small, very dangerous and on the increase thanks to Biomass burning.

You can ...

Reduce cooking, burning candles, and smoking will greatly reduce the particle levels in a home. Hoovering with a cleaner that does not have a dust filter will stir up and greatly increase particle levels in the air.
