Typical Replacement Interval: Approximately every 6 months, depending on water quality, sediment levels, and water usage.
20 Micron Filter: Replace sooner if flow decreases, pressure loss increases, or the cartridge becomes heavily clogged or discoloured.
1 Micron Filter: Replace sooner if flow decreases or pressure loss becomes excessive.
UV Lamp: Replace approximately every 12 months, according to the manufacturer's specified lamp life.
Quartz Sleeve: Inspect and clean regularly. Replace if cracked, damaged, or heavily scaled.
Quartz Sleeve O-Ring: Inspect annually and replace if damaged or deteriorated.
Best Used With
Coarse sediment pre-filter for high-sediment water.
Activated carbon filtration where chlorine, taste, or odour reduction is required.
Additional treatment for high iron, manganese, hardness, or turbidity.
Multi-stage filtration systems for improved water quality and equipment protection.
Not Suitable For
Dissolved salt or TDS reduction.
Water softening or hardness reduction.
Chlorine, taste, or odour reduction without carbon filtration.
Dissolved chemical contaminant removal.
Significant iron or manganese removal without suitable pre-treatment.
Heavy sediment loads without suitable pre-filtration.
