GROHE Blue CO₂ bottles: compatibility and replacement

Use only CO₂ cylinders specified for GROHE Blue Professional. When carbonation weakens or stops, exchange the cylinder — the tap keeps delivering filtered still water in the meantime. Cylinders are exchanged, not thrown away.

Compatibility

Cylinder threads and pressure ratings are system-specific. Reordering from your registered system in My GROHE Blue shows only the cylinders that fit yours.

Signs a cylinder is empty

  • Sparkling output becomes noticeably softer.
  • Medium and sparkling settings taste the same as still.
  • The system reports the cylinder as depleted.

Next step

Filters, CO₂ and cleaning cartridges matched to your system.
