Common questions
- Which water filter fits the Zip HydroTap G4 Cube?
- The Zip HydroTap G4 Cube takes the Zip GlobalPlus 0.2 micron filter cartridge 91290 (G4 HydroTap). HydroTaps made before February 2017 take 91290 (it replaces 91291). A G4 made after then may take 93701, so check the code on your current cartridge. Compatible filters made to the same specification also fit.
- How often should I replace the water filter in my Zip HydroTap G4 Cube?
- 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 91290 in Australia?
- We track 4 Australian sellers for the 91290; the lowest listed price when we last checked was A$74.95 at eBay AU. Prices are re-checked daily and dated on this page.
- How do I fit the 91290 in a Zip HydroTap G4 Cube?
- No tools, a few minutes: 6 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.
- How do I reset the reminder?
- After the flush, go to Menu > Installation > Filter reset and press Internal filter; the filter percentage on the home screen goes back to 100%.
