Multi-stage filtration

Reverse-osmosis replacement filters

RO systems may use sediment filters, carbon filters, a membrane and a post-filter on different schedules. Match the complete system—not just the cartridge dimensions.

Record the system and every stageConfirm the model, number of stages and membrane capacity. A 50-GPD membrane should not be treated as interchangeable with a 75-GPD membrane.

RO stages do not all expire together

Pre-filters commonly protect the membrane and may be replaced more often. Membranes and post-filters can follow different schedules. Use the manual for the exact system and account for local water quality and usage.
