Watch the guide or follow the steps.
- 1Put a container under the filter to catch drips.
- 2Turn off the water and open the filtered tap to let the pressure out.
- 3Pull the tubes out of the push-in fittings at each end of the old cartridge and throw the cartridge away.
- 4Unwrap the new cartridge and push the tubes into each end, with the flow arrow pointing the way the water runs.
- 5Turn the water back on, check for leaks and run the tap for 5–10 minutes; milky water is just air and clears.

Common questions
- Which water filter fits the Puretec X3?
- The Puretec X3 takes the Puretec IL149Q inline cartridge (1 micron, KDF/carbon) for X3.
- How often should I replace the water filter in my Puretec X3?
- Every 12 months. Flow slows and performance drops off as the filter fills up, so it's worth doing on time.
- Where can I buy the IL149Q in Australia?
- We track 2 Australian sellers for the IL149Q; the lowest listed price when we last checked was A$173.00 at Cass Brothers. Prices are re-checked daily and dated on this page.
- How do I fit the IL149Q in a Puretec X3?
- No tools, a few minutes: 5 steps, listed on this page with the replacement video where the maker has one.
- What happens if I don't change it?
- The carbon stops reducing chlorine taste and odour and the flow from the tap slows as the cartridge clogs; a boiling-water tap with a scale-reducing filter builds scale in its tank faster.
- Is there anything to reset afterwards?
- No reset light. Write the date on the cartridge.
