PM2.5 is one of the standards to measure air quality which takes stock of concentration of particulate matters with a diameter of less than 2.5 micrometres in the environment that can penetrate deep into the lungs even when one is wearing facial masks. These particulate matters mostly come from smoke emitted by vehicles and factories.
