Triple-Stage Pre-Filtration & Pump Protection

The system is fitted with a triple 20” × 2.5” filter housing assembly, consisting of:

• 5 micron sediment filter

• 10 micron carbon block

• 1 micron sediment filter

These cartridges are installed specifically to protect the RO pump and membranes and are not intended as full system pre-treatment. Routine cartridge replacement is essential to minimise pressure loss, prevent fouling, and ensure long-term system reliability.
