With the Philips/Saeco AquaClean CA6903/22 Water Filter 2 Units, you can make 1,250 cups of coffee in succession, without having to descale your espresso machine in between. The package comes with 2 Aquaclean filters that you can use one after the other. It's possible to replace the filter up to 8 times, so that you can postpone descaling until after 5,000 cups of coffee. The filter removes even the smallest lime particles from the water, preventing limescale from entering the pipes of your espresso machine. Not only will your espresso machine last longer, but the coffee will continue to taste good. Limescale affects the flavor of the coffee and the pressure with which the water flows through the pipes.Suitable for: Philips EP3100 series; Philips 4000 series; Philips 5000 series; Saeco Incanto; Saeco Picobaristo; Saeco Intelia Deluxe; Saeco Granbaristo.
