Quooker CUBE Filter & Replacement Guide
Quooker Water Filter & Cartridge Guide
If you have a Quooker CUBE system, the water filter is an essential component. This guide explains how the filter works, when to replace it, and how to maintain your CUBE water quality.
Does Every Quooker System Need a Filter?
Only Quooker CUBE systems require a filter. The CUBE filters water before chilling and carbonating it. Standard Quooker boiling water systems (without CUBE) do not require a filter — the boiling process naturally kills bacteria and the water quality depends on your mains supply.
How the CUBE Filter Works
The AC-HF filter cartridge is installed between your cold water supply and the CUBE unit. It contains activated carbon that:
- Reduces chlorine taste and odour
- Removes sediment and particulate matter
- Improves the taste of both still and sparkling water
- Reduces limescale deposits in the CUBE system
When to Replace the Filter
- Recommended replacement: every 6 months
- Signs it's time to replace: reduced water flow, noticeable chlorine taste, or the CUBE indicating a filter change
- Filter lifespan: approximately 1,000 litres of filtered water
How to Replace the AC-HF Filter
- Turn off the water supply to the CUBE system
- Disconnect the old filter cartridge by pressing the release button and pulling the fitting
- Connect the new AC-HF cartridge in the same orientation (arrow direction = water flow direction)
- Turn the water supply back on
- Flush 5 litres of water through the CUBE before drinking (to remove any carbon dust from the new filter)
The replacement takes approximately 5 minutes and requires no tools.
Other Quooker Water Treatment Options
Even without CUBE, some Quooker owners choose to add an inline water filter for improved taste. The standard Quooker AC-HF filter can be installed inline on the cold water supply to your tap, reducing chlorine and improving water quality for all cold water use.
Compatibility
The AC-HF filter cartridge is compatible with all Quooker CUBE systems. It is also compatible with standard Quooker boiling water systems when used as an inline filter.
