Delhi the capital of our country is one of the most populated and polluted cities in the world and people die every year due to wide exposure to air pollution. Air pollutants are present in the atmosphere in the form of minute solid particles, liquid droplets and in the form of gases which are responsible for producing hazardous effects in human, animals and plants. Examples of outdoor pollution are smog, emissions of dangerous gases from vehicles, power plants and industries. Indoor air pollution is 10 times more dangerous than outdoor air pollution, because the pollutants are present in more concentrated form than present in outdoor air and further, people spend more time in indoors than the outdoors. The indoor air toxins cause signs of premature aging on the skin, because skin naturally loses its moisture and elasticity and people look older at a very early stage. To minimize the hazards of indoor air pollution, installing air purifiers in the homes is the best possible way to save the lives of the family members. Air purifiers are the instruments that help in removing pollutants from the air and so, improve the quality of air. These appliances are very useful for the patients suffering from asthma, respiratory disorders and allergies. These can be easily installed, for residential and commercial (schools, hospitals, industries, etc.) purposes. Air purifier consists of a HEPA (high efficiency particulate air) filters that help in purifying the surrounding air by removing 99.9% dust particles greater than 0.3 microns, pollen, pet dander smoke and all the pollutants present in the air. Thus, air purifiers make the environment dirt and odour free, which are the root cause of all the types of infections and allergies and produce harmful effects. Indoor air quality can also be improved by creating no smoking zone, keeping the floor neat and clean, only use natural methods for cleaning and avoid the use of synthetic air fresheners.
