  1. 1Have a bucket and a cloth ready. On the screen go to Menu > Installation > Filter Flush, then open the filter door on the front of the command centre.
  2. 2Find the flush line behind the cartridge, put its end in the bucket and turn the stop cock on and off quickly to release the pressure.
  3. 3Hold the cartridge, press the red lever at the top right (units made after 2017 have no lever), turn it a quarter turn to the left and pull it down.
  4. 4Write today's date on the new 91290, wet the O-rings, push it up into the head and turn it a quarter turn right so the label faces forward.
  5. 5Open the stop cock, press Start and run at least 10 litres through, then close the stop cock and press Stop.

Common questions
What does the 91290 fit?
The Zip GlobalPlus 0.2 micron filter cartridge 91290 (G4 HydroTap) fits 6 Zip models, including the HydroTap G4 All-in-One, HydroTap G4 Arc and HydroTap G4 Classic. Every one is listed on this page. Compatible filters made to the same specification also fit.
How often should I replace the 91290?
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?
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%.
