Electrospun Nanofiber Filters with Minimized Pressure Drop for Indoor Air Quality Control: A Design and Fabrication Approach
Electrospun nanofiber air filters can achieve excellent particle filtration efficiency and low pressure drop. Therefore, they can potentially be applied in buildings for controlling indoor particulate matter concentrations. To improve filtration performance, this study developed a design and fabrication approach for electrospun nanofiber air filters with minimized pressure drop and optimized structures. First, this research developed semi-empirical models for calculating the pressure drop and PM2.5 filtration efficiency of nylon electrospun nanofiber filters using the fabrication parameters of electrospinning time and nylon concentration. With the proposed models, this investigation then proposed an optimization approach to minimize the pressure drop of the nanofiber air filters. For a given air velocity and PM2.5 filtration efficiency, one can minimize the pressure drop by finding the optimal solution concentration, while the target PM2.5 filtration efficiency can be achieved through adjustment of the electrospinning time.
