Description
Reduce hardness minerals and scale before they reach sensitive RO components
The Omnipure K5654-BB is an inline ion-exchange softening cartridge designed to reduce calcium and magnesium hardness. Used as pretreatment, it can help limit scale buildup on RO membrane surfaces and in small point-of-use filtration components.
What this media is designed to do
Hardness ReductionIon-exchange media helps reduce calcium and magnesium hardness.
Scale ControlHelps limit mineral scale on membrane surfaces and downstream equipment.
Approx. 500 GrainsSource lists approximately 500 grains of hardness capacity.
Made in USAManufactured by Omnipure.
Useful information
Softening changes mineral composition rather than making water “healthier.” It can improve scale control and system performance. Because ion-exchange softening typically exchanges hardness ions for sodium or another counter-ion, customers on sodium-restricted diets should evaluate their overall water source and system design if this is a concern.

David M –
This filter definitely improved the softness of our water. Soap lathers better, and no more chalky taste. I noticed a slight drop in flow rate after 6 months, but that’s expected. Just replaced it and back to normal. Solid product.
