What to do avoid the fine particulate matter

We use particle counter to check air quality around us.
The handheld particle counter tell use both PM2.5 and PM10. also 0.3μm and 2.5μm.
We can use air purifier in home, and also some plants.
Air purifier can clean the bad air ,and the plants can filter bad air too.
