The pleated design increases surface area and maximizes dirt holding capacity
Can be washed with clean water to increase the effective lifespan
Polyester cellulose media is bacteria and chemical resistant
Versatile and reusable, allowing for a variety of uses
Low-pressure drop and high flow rate
The filter media has a pleated design around a polypropylene core for added strength and the ends are completely molded into a vinyl plastisol base (big blue housing). 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. There are available replacement cartridges when it's time for a replacement.
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.
