Clean air is our fundamental right. But, do you think we breathe in clean air? I’m sure the answer is no; unless you live in the mountains. We all know air pollution is a major cause of various health problems. Therefore, it’s imperative to breathe clean air. However, it’s not always possible to control the quality of air that we breathe in. But, sometimes it is; especially when you are at home or office. It is proven that indoor air presents the same health risks.
