Air filtration has a wide range of applications including hospitals, HVAC systems, indoor air purifiers, mini purifiers for cars and industries with heavy dust environment. So, there is need to optimize the air filtration systems in terms of lifetime, reduce energy consumption, maintenance and operating costs. Numerous studies were carried on the air filtration systems especially on the filtration mechanisms and filtration media. Several numerical models were developed to predict the flow through the filter media. This triggered the development of filters with pleats which increases the filtration efficiency, dust loading capacity by increasing the effective area of filters. In the present work, using the computational fluid dynamics package FLUENT in ANSYS Workbench 14.5, the main concern is that how the pleat shapes of filters in the indoor air purifier will affect its performance. To study performance, the effects of pleat geometry parameter like pleat thickness, pleat area on the pleat shapes were investigated on commercially available HEPA Pleated filter with indoor environment. An assumption was made that Darcy’s law was applicable to the current analysis since it requires laminar flow only to avoid noise in air purifier and turbulence.
