AQUAPHOR Crystal-H Under-Sink Kitchen Filter

Dealing with hard water, but don’t want the complexity of a full mechanical softener? The AQUAPHOR Crystal-H under-sink system is a simple, smart point-of-use solution designed to soften moderately hard water while deeply filtering out common municipal toxins, allergens, and aggressive chemical compounds. Operating smoothly without internal noise or bulky storage tanks, it delivers refreshing, clean water straight from your kitchen tap.

Deep Sorption

Removes chlorine, heavy metals, pesticides, and common household allergens.

Targeted Softening

Reduces limescale build-up to protect and extend the life of your kitchen appliances.

Regenerable Media

The ion-exchange resin module can be easily regenerated at home up to 4 times using salt.

6,000L Capacity

Filters up to 6,000 litres with a steady, fast-flowing delivery rate of 2 litres per minute.

The Science-Backed Benefits of the AQUAPHOR Crystal-H

The AQUAPHOR Crystal-H features multi-stage block filtration optimised for everyday domestic use. At its core is patented Aqualen™ ion-exchange fibre, which provides 42 times the surface contact area of standard granular carbon filters. This dense structural configuration creates an incredibly reliable pathway that captures heavy metal ions and trace chemical impurities with exceptional efficiency.

By pairing this deep-cleaning carbon block technology with a dedicated ion-exchange softening module (Cartridge KH), the system effectively isolates and removes the raw hardness salts that lead to mineral scale. This ensures that your drinking water remains clean and scale-free, without dropping your countertop water pressure.

Your Life with the AQUAPHOR Crystal-H

Imagine pouring a crisp glass of water directly from your tap—completely free of harsh chemical smells, chlorine tastes, or unsightly limescale flakes floating in your freshly brewed tea. Because the entire system tucks neatly beneath your sink counter, it keeps your counter and cabinet footprint clear of bulky, complex machinery. It provides a simple, maintenance-friendly approach to water purification that elevates your daily kitchen rituals.
