Quooker Flex Square

Yes – every Quooker tap comes with a built-in HiTAC filter inside the boiling water tank, which enhances the taste of the boiling water. This carbon-based filter effectively removes contaminants and impurities, absorbing chlorine, pesticides, and organic pollutants to deliver water that looks, smells, and tastes fresher.

If you have a Cube or Cold Water Filter installed, your drinking water will be filtered as well.

Please note: The HiTAC filter is not designed to remove limescale. For more details on limescale filtration, click here.

Yes – typically, it is, depending on the age of your unit. The CUBE is compatible with all Quooker systems manufactured after October 2017.

The Quooker CUBE should be equipped with an active carbon filter and a hollow fibre filter. Together, these filters effectively remove bacteria, chlorine, chemicals, and pesticides, resulting in water that tastes and smells fresher. This AC + HF filter has to be bought separately

If your Quooker’s sparkling water has lost its fizz, it’s time to replace the CO₂ cylinder.

To do this, simply unscrew the empty CO₂ canister from the white plastic holder at the top by turning it counterclockwise. Next, remove the plastic wrapper and red cap from the new CO₂ canister, and then screw it into the holder clockwise. You'll hear a slight hiss as you tighten it—continue until no more gas escapes.

New CO₂ canisters are available in a set of four.

If you live in an area with hard water, such as the French Riviera, limescale may have built up at the end of your tap, causing reduced water flow.

Try removing the nozzle and taking out the aerator. Soak it in a small cup of white vinegar for about one hour, then rinse away any remaining limescale and reassemble the tap.

If the issue persists, there may be limescale inside the tank, which will need to be cleaned.
