Indoor environments contribute significantly to total human exposure to air pollutants, as people spend most of their time indoors. Indoor air quality is influenced by penetrating outdoor air, specific indoor pollution sources, interactions between building system/construction techniques and occupants. Some pollutants may be 2-5 times more concentrated inside than outside buildings . Since people spend most of their time indoors, so the quality of indoor air has major implications for health and can contribute to a wide spectrum of respiratory health effects, from allergic sensitization to cancer. Natural pollutants such as allergens, dampness and mould and radon can also have significant health effects. Reflecting the complexity of indoor pollution, the most effective ways to reduce its impact are home based, multi component interventions. Research shows that many common houseplants and blooming potted plants can improve inmates health by helping to fight these pollutants in the home. While it’s common knowledge that plants absorb carbon dioxide and release oxygen as part of photosynthesis, research by the National Aeronautics and Space Administration (NASA) also confirmed that plants eliminate harmful gases from the air. So looking into the importance of plants in our lives, the study was planned out to assess the role of selected plants in improving indoor environment. Results indicated that in all the rooms where indoor plants were placed showed improvement in air quality both in the case of carbon-di-oxide where majority of the houses lie in limit 501-999 ppm and in case of Carbon-monoxide majority of the houses lie in limit 0-3.5ppm. All the areas showed that both the gases were well within the permissible limit (permissible limit 1000 ppm for carbon-dioxide whereas permissible limit 9ppm for carbon-monoxide). Further, in all the rooms where indoor plants were placed showed improvement in humidity level where majority of the houses had humidity limit above permissible limit of 60% and temperature limit above 24oC respectively.
