Replacement cartridges
Every system has its own cartridge set. Pick your system to see the stages, when each is replaced and what it costs — we fit them at your home and pressure-check afterwards.
Tank filter cartridges (steel)
Cartridges for the steel 40 / 30 / 20 / 10 tank filters — replaced at your home, pressure-checked after.
Triple Jumbo cartridges
Three 20-inch jumbo stages — replaced together as one set.
RO kitchen filter cartridges
Stages for the RO kitchen filter — pre-filters every few months, membrane and alkaline every two years.
Or leave the schedule to us — the annual maintenance contract
A visit every 3 months: we replace cartridges on schedule (cartridge cost as agreed), check every joint, and measure and record your water quality. One fee a year.
Not sure which cartridges your system takes?
Three checks are enough, and all of them are visible:
- 01A steel cylinder at the main inlet or beside the tank?That is a steel central filter — the size is on the label (10 / 20 / 30 / 40). Cartridges: central filter cartridges.
- 02Three large blue housings on a frame?That is the Triple Jumbo, on 20-inch cartridges. Cartridges: Triple Jumbo cartridges.
- 03A unit under the kitchen sink with its own tap?That is the RO or DG kitchen filter — if it has a small white tank, it is the RO. Cartridges: kitchen & RO cartridges.
Still unsure? Send us a photo of the system — we will identify it and tell you which cartridges it needs.
