PM2.5 are the smaller particles, yaar, tinier than a hair, while PM10 are bigger. Honestly, the PM2.5 is more dangerous because it can slip deep into your lungs and mix right into your blood. It's why I spent so much on that purifier for our Bangalore flat—after Diwali, my daughter's cough just wouldn't leave her chest. The bigger PM10 might make you sneeze, but it's that silent, fine dust you can't even see that truly frightens a parent.
