POLY-PLEAT cartridges meet or exceed the three-log (99.9 percent) removal requirements described in National Sanitation Foundation Standard 53 for cyst-sized particles. They are ideal in controlling cryptosporidium, giardia cysts and other harmful microorganisms, and as final fil-ters for municipal water filtration without pre-filtration required. In high turbidity water, pre-filtration is recommended using Harmsco sediment cartridges with two or three-step filtration, depending on the source water. They provide long filter life due to their pleated design and increased surface area.
