Purity Plus cartridges uses a highly controlled and state of the art process involving molten polypropylene fibers and a patented takeoff system. Gradient depth filtration is achieved with their technically advanced design where the innermost fibers form a tight self-supporting structure that eliminates the need for a separate center core and provides exception strength.
As a depth filter, Purity Plus sediment cartridges trap particles throughout the entire cross section of the filter. The gradient density design allows for optimum dirt holding capacity and minimal change-outs.
