Filters of different kinds purify the air that people breathe and the water that people drink. The environment today has become more polluted than before due to the exhausts of various industrial structures, vehicles and more. And even without these additional pollutants, the air especially in the city is naturally filled with dust particles floating around. This is harmful to one’s health when dirty air is inhaled. It can cause many illnesses and conditions to the lungs. People of old age and little children tend to be affect more easily since their lungs are more delicate and they are more vulnerable and susceptible to these illnesses.
