Air pollution is one of the most concerned issue worldwide as it affects the population at a time. Indoor air contamination can be due to different forms of allergens, smoke, mold, radon, and other pollutants all negatively impact the health of building occupants. These pollutants can have severe effects on health of individuals up to 10 times worse than the outdoor air pollution due to lack of ventilation. For purification of air an attempt has been made to construct a purifier using filters that can trap the indoor air pollutants. The prepared model is constructed considering the cost and working efficiency for maintaining a healthy indoor environment. The model is based on the filtration of air through compact filters (HEPA filters) that are more efficient than any other filters. To analyze the indoor air quality and the working efficiency of the purifier, certain quantitative analysis of the air micro-flora and the total mass concentration of the indoor dust were conducted at four locations in the premises of B. K. Birla College (Autonomous), Kalyan. Quality of the indoor air before using the Constructed Indoor Air purifier and during the use of purifier was checked. The resulted data showed a decrease in the microbial population as well as reduction in the concentration of dust particles, thus indicating the working efficiency of the constructed purifier.
