Under-sink water filter GROHE 40547001 White

The GROHE 40547001 White under-sink water filter is designed to provide clean, improved-tasting drinking water while installed discreetly beneath the sink. Intended for regions with soft water (below 9° dKH), this compact white filter integrates with GROHE Blue systems to deliver filtered water directly from the tap without occupying counter space. The unit uses a three-phase filtration process that reduces coarse particles, removes taste- and odor-causing substances with activated carbon, and performs a fine filtration step to capture small residual particles. The filter is compatible with GROHE Blue Home, GROHE Blue Professional and GROHE Blue Pure systems and has a rated capacity of up to 3000 litres when used in suitable water conditions.

Advantages

The GROHE 40547001 combines a compact under-sink design with a three-stage filtration approach that targets dirt, taste-affecting substances and fine particulates. Its compatibility with multiple GROHE Blue systems allows straightforward integration into existing setups. The white finish makes it visually neutral for installation under most sinks, and the cartridge format enables a simple replacement procedure when the filter is spent.
