Key Maintenance Principles
Replace on schedule, not on symptoms. By the time you notice a taste change or pressure drop, the cartridge is well past its service life. Set a calendar reminder when you install a new cartridge.
Hard water areas need more frequent replacement. In Perth and Adelaide, replace cartridges at the shorter end of the range. In Melbourne and Sydney, the longer end is usually fine.
Keep spares on hand. Browse our replacement cartridge range and order your next cartridge when you install the current one.
How do I know when to replace my water filter cartridge?
Replace on schedule (6–12 months depending on system and water hardness) regardless of taste or flow. Don’t wait for symptoms — an exhausted cartridge provides no filtration. Browse our replacement cartridge range.
