Abstract: This paper describes the maintenance of indoor air quality by using the polyacrylonitrile filters (PAN). The PAN filters where placed in-between the jars to find out the air filtering capacity of these filters. The main objective of this is to develop high efficiency filters thereby reducing the environmental pollution. The polymers that have a strong attraction to main components of smog, particularly particles that are smaller than 2.5 microns, known as PM2.5. Current filtrations systems that can remove them from the air are very energy intensive. It turned out that polyacrylonitrile (PAN), a material commonly used to make surgical gloves, met these requirements. Using a technique called electro spinning , liquid PAN was converted inoses a serious health threat to the public as well aa influencing visibility, direct and indirect radiative forcing, climate,and ecosystem. Particulate matter is a complex mixture of extremely small particles and liquid droplets. these days people tend to spend more time indoor. According to a study peolpe spend 90% of time indoor. Now-a-days staying indoor becomes unsafe due to poor indoor air quality
