Explain the effect of the increase in the level of air pollution, on the market demand for ‘‘Air Purifiers’’.


Market demand refers to the quantity of a commodity that all the consumers are willing and able to buy, at a particular price during a given period of time. If the pollution in air increases, the demand for air purifier will also increase. This will lead to a rightward shift in the market demand curve.
