About your Puretec Z1-T3
Puretec filtered water tap, tap or under-sink system — Puretec Z1 Tripla filter and tap kit. Its water filter is the Z1-R Ultra Z quick-twist cartridge (0.1 micron), part Z1-R, changed every 12 months.
Where the model number is: On a boiling or chilled water tap the model is on the label on the unit under the bench, not on the tap itself. On an under-sink system it is on the filter head or housing; the cartridge code is printed on the old cartridge.

Common questions
- Which water filter fits the Puretec Z1-T3?
- The Puretec Z1-T3 takes the Puretec Z1-R Ultra Z quick-twist cartridge (0.1 micron). Puretec says to change it every 30,000 litres or 6 months, whichever comes first, on Tripla kits. Compatible filters made to the same specification also fit.
- How often should I replace the water filter in my Puretec Z1-T3?
- 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 Z1-R in Australia?
- We track 5 Australian sellers for the Z1-R; the lowest listed price when we last checked was A$91.66 at eBay AU. Prices are re-checked daily and dated on this page.
- How do I fit the Z1-R in a Puretec Z1-T3?
- 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.
