Triple Big White/Blue Polyspun Sediment Filter Cartridge MWF 20″ x 4.5″
These pleated cellulose cartridges are manufactured from a durable, non-woven polyester material that is suitable for a wide range of filtration uses. The filter media is pleated around a polypropylene core for added strength and the ends are completely molded into a vinyl plastisol base. Embedding and sealing each end of the pleated media in this fashion fuses the three components together forming a unified end cap and gasket. The overlap seam is sonically welded to reduce internal bypass improving filtration efficiency.
The 20″ x 4.5″ Full Flow/Big Blue version has more than 16 square feet of filtration surface area. The media is pleated to maximize dirt-holding capacity and extend the time period between changes or cleaning.
