You are buying the CO2 bottle (+valve) and the gas inside! You own the bottle, making refills much easier and more convenient.

As you have one 425 g CO2 bottle within the GROHE Blue Starter kit that you bought, you have to buy one 425 g CO2 Starter kit (40 422 000), which includes four full bottles. In total you will have five CO2 bottles. Once four bottles are empty and the fifth bottle is in use, you can order a 425 g CO2 refill (40 687 000) from the GROHE webshop.

Don‘t put the CO2 bottle in your normal house waste. Instead take it to a specialist for waste management or back to GROHE. Please note GROHE will refund any money for any costs you may incur in returning the bottle.

Up to 60 litres - it depends on whether you are drinking medium or full sparkling water.

No, a maximum of 2 bar pressure can remain in the CO2 bottle. The return shippment of the 425 g CO2 bottles is only possible by UPS!

The filter has to be changed at least every 12 months, or when it has run out, whichever is sooner. An LED display in the faucet’s left handle makes it easy to tell when filter capacity is running low. A flashing light indicates less than 10 % capacity and a rapidly flashing orange light indicates 1 % capacity, meaning the filter cartridge must be changed. When the time comes to replace the filter, the display on the tap will alert you with an orange, blinking light.

The filter can be easily disposed of as normal plastics.

The filter can be easily changed simply by unscrewing it and screwing in the new filter in its place. You don’t even need to turn the water supply off.
