Replacement Water Filters & Elements
6 Items
Every Clearbrook system is built so the housing outlasts the filter. These are the elements that go inside it.
The CB9 is the original design — 9 inches tall, two and a quarter wide — and we've sold more than three million of them over the past twenty years. The CB5 is the second generation: 5 inches by 3, using the identical formulation, media and gram weight. The difference is shape. Because the CB5 is shorter and wider, it stays fully submerged for longer as the reservoir empties, which keeps the flow rate steadier through the cycle. Both fit Clearbrook gravity systems.
The PF2 Fluoride & Arsenic Reduction Elements attach to your existing gravity elements, with independent testing showing typical fluoride reduction above 95%. For under-sink and refrigerator systems, the Dual Stage and GEN4-210 cartridges are here too.
Replacement intervals depend on how much water you run and what's in it — the FAQ covers how to judge it.
