RO kitchen filter cartridges
Stages for the RO kitchen filter — pre-filters every few months, membrane and alkaline every two years.
Quoted on request — it moves with each shipment. We confirm it before any commitment, or it sits inside the annual service contract at a fixed price.
The stages — what each does and when it is replaced
Stage 6 — restores alkaline balance to the water after reverse osmosis.
Stage 7 — puts beneficial minerals back into the water after reverse osmosis.
Intervals are a guide — they depend on your area's water and your usage. At the free test we tell you the right schedule for your home.
Fits these systems
