Running the system
Filters and CO₂
How filter cartridges and CO₂ cylinders are replaced, and how My GROHE Blue keeps replacements compatible.
The filter cartridge is a consumable. Your tap or app indicates remaining capacity, and replacement intervals depend on local water hardness and household usage — an adviser can confirm the expected interval for your emirate.
GROHE Blue Professional uses CO₂ cylinders for sparkling water. Pure has no carbonation and never requires CO₂, which is why the builder does not offer CO₂ items on a Pure configuration.
My GROHE Blue records the exact system registered to your address, so reordering only ever shows consumables that fit it.
