- 4-in-1 PCB Composite Filter (RO-PCF-3008) – Multi-stage cartridge that captures sediment and reduces chlorine/odors before water reaches the RO membrane. Typical life: about 1 year.
- 600 GPD RO Membrane (MEM-RO-4108-600) – High-efficiency spiral-flow membrane that removes dissolved solids for pure, clean water. Typical life: 2–3 years.
Actual lifespan varies with water quality and usage. Replace sooner if flow slows or taste/odor returns.
