Micron range fiber has been used for air filtration applications such as commercial and industrial. Protection for individuals from outdoors can be achieved by facial masks, indoor air relies heavily on energy-intensive air filter devices. Although electrospinning was known to be a success in producing nanofibers, this paper will focus on electrospinning methods to produce microfibers which will be applied in the filtration application. Electrospinning allows to create microfibers like the known nanofibers that can be collected to form non-woven fabric applied in the filtration media. These fibers increase filtration efficiency at relatively small decrease in permeability. To achieve such optimum micron range diameters, working parameters must be considered while maintaining the fibers morphologies. The parameters will be closely selected by using the design of experiment. These parameters can be branched into factors and levels from the solution, process and external parameters while only considering Poly-vinyl alcohol as the source of polymer to get maximum results in air filtration media. Once the optimum poly-vinyl alcohol polymer micron size fiber diameter has been obtained, the results will in two-dimensional scale will be discussed and concluded in with comparison to the filtration efficiency
