Water Filter Maintenance: How to Get the Most from Your System

March 11, 2024 2 min read

A water filter is only as good as its maintenance. Here’s a practical guide covering all the main filter types used in Australian homes.

The Golden Rule: Replace on Schedule, Not on Symptoms

Most filter media exhausts gradually with no visible or taste-based warning. By the time you notice a change in taste or smell, the cartridge has been underperforming for weeks. Set a calendar reminder when you install a new cartridge and replace on schedule regardless of how the water tastes.

Maintenance by Filter Type

Filter Type Key Maintenance Tasks Schedule
Benchtop/cooler cartridge Replace cartridge; scrub ceramic outer shell monthly 6–12 months
Under-sink filter Replace cartridge; check O-ring; check for leaks 6–12 months
RO system Replace pre/post carbon filters; replace membrane Filters: 6–12 months; membrane: 2–3 years
Shower filter Replace cartridge 6–12 months
Whole house filter Replace sediment cartridge; replace carbon cartridge Sediment: 3–6 months; carbon: 6–12 months

Cleaning the Reservoir (Benchtop and Cooler Systems)

Clean the reservoir every 3–6 months with a mild food-safe sanitiser. Rinse thoroughly before refilling. This prevents biofilm buildup in the lower chamber.

Checking for Leaks (Under-Sink and Whole House)

Check all connection points monthly. A small drip caught early prevents water damage. If you find a leak you can’t fix by tightening the connection, call us on 1800 789 781.

Can I clean and reuse my water filter cartridge?

The outer ceramic shell of a ceramic dome filter can be scrubbed to restore flow rate. The internal filter media (carbon, KDF, activated alumina) cannot be regenerated at home — replace on schedule.
