Watch the guide or follow the steps.

- 2Take all the wrapping and caps off the new cartridge.
- 3Turn the old cartridge a quarter turn anticlockwise, pull it down out of the head and throw it away.
- 4Push the new cartridge into the head and turn it a quarter turn clockwise until the arrows on the head and cartridge line up (SPARQ: until it stops and the lock labels line up).

Common questions
- What does the Z7-R fit?
- The Puretec Z7-R PureMix quick-twist cartridge (1 micron, for harsh water) fits the Puretec PureMix Z7. Compatible filters made to the same specification also fit.
- How often should I replace the Z7-R?
- Every 6 months. Flow slows and performance drops off as the filter fills up, so it's worth doing on time.
- Where can I buy the Z7-R in Australia?
- We track 5 Australian sellers for the Z7-R; the lowest listed price when we last checked was A$92.58 at eBay AU. Prices are re-checked daily and dated on this page.
- How do I fit the Z7-R?
- 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.
