Why It Matters

You've Already Invested - Now It's About Protecting It

Your system was installed to give you clean, great-tasting water for years to come – but that only holds true if the cartridges are replaced on schedule. Staying up to date isn’t a new cost, it’s maintaining the investment you’ve already made.

Skipping a replacement doesn’t just mean weaker performance – it means cartridges that have reached capacity are no longer removing what they’re designed to remove, and the water quality you paid for starts to slip without you noticing straight away.

When Do I Need to Replace My Filters?

  • Smell or Taste Returns

    If water starts tasting or smelling the way it did before your system was installed, your cartridges have reached their limit.

  • Skin Feels Dry

    A noticeable drop in pressure at the tap is often the first sign a cartridge is clogged and overdue for replacement.

  • Reduced Water Flow

    A noticeable drop in pressure at the tap is often the first sign a cartridge is clogged and overdue for replacement.

Even if you haven't noticed any of the above, we recommend replacing your cartridges annually to stay ahead of it.
