Kitchen accessory designed to keep water clear and reduce limescale in fully automatic coffee machines. Philips Domestic Appliances Water Filter CA6903 combines microporous filtration and ion exchange for cleaner water and steadier machine performance. Is fitting a filter a better route than frequent manual descaling for your machine?
⚡ At a Glance
- • Water Quality: Microporous filtration and ion exchange reduce fine particles and mineral deposits for clearer water
- • Best for: Owners of compatible Saeco or Philips fully automatic coffee machines with an AquaClean sticker
- • Not ideal for: Machines without AquaClean compatibility or users requiring integrated hands-free features
Microporous filtration traps the smallest dust particles while ion exchange reduces limescale formation. Patented water flow protects the water circulation for steady performance.
Protects internal circuits from scale - with ion exchange technology
Ion exchange substitutes hardness ions in the water, reducing the minerals that form limescale inside water pipes and heat exchangers. The process lowers deposit formation where water heats and circulates.
Less limescale means fewer manual descales and more consistent heating performance over time for compatible machines.
Cleaner water for clearer flavour - with microporous filtration and patented water flow
A microporous filter captures very small dust and sediment particles, while a patented water flow design maintains steady circulation through the filter. Together they limit particulate carry-over into the brew cycle.
Cleaner water helps preserve the delicate flavour of coffee, so brews taste clearer and machines avoid sediment buildup.
Simple maintenance and timely swaps - with Click and Go insertion and menu reminders
Click and Go enables straightforward fitting of the filter into the water tank, while compatible machines can activate a menu-based reminder when a change is required. No special tools are needed for replacement.
Quick, tool-free replacement and clear prompts reduce guesswork and make upkeep straightforward for regular users.
