Most frequent questions

  • How much sparkling water can I get from one CO₂ cylinder? CUBE

    The CO₂ cylinder is filled with enough carbon dioxide for around 60 litres of sparkling water. The cylinders are available per set of 4 in our webshop.

  • What is filtered by the CUBE? CUBE

    The CUBE is equipped with an active carbon filter and a hollow fibre filter. The filter ensures a better water quality because it filters bacteria, chloride, chemicals and pesticides from the water.

  • How long do the filters last? CUBE

    For hygienic reasons, the filters should be replaced every 12 months, regardless of the amount of water used. After 12 months, the CUBE will start beeping and the light on the CUBE tank will flash to indicate that the filters need to be replaced. The filters can be accessed under the sliding panel on top of the CUBE. Instructions for replacing the filters are printed on the filter cartridges.

    New filters are available in our webshop.
