How would you like to connect the filter?
Should pollutants, chlorine and off-tastes be filtered out?
Should germs and bacteria be held back?
Should the filter also reduce limescale?
Is PFAS contamination a concern for you?
Do you sometimes see sediments such as sand or rust in your aerator?
Where does your water come from?
How would you like the filter to be connected?
Here you have to choose
On the tap, the cartridge comes either with germ filtration or with a PFAS stage – both together only under the sink. Your recommendation therefore covers one of the two points, the alternative covers the other.
If both matter to you, go back to the first question, choose “under the sink” and take a look at the Fusion PFAS: it filters germs and PFAS in one unit.
You can only get both together under the sink
On the tap, you can have the certified germ barrier or the PFAS stage – only the Fusion PFAS under the sink can do both. For the tap, your recommendation focuses on the germ barrier.
You can only get both together under the sink
On the tap, a cartridge filters either pollutants or germs. The Fusion under the sink has both stages in one unit. For the tap, your recommendation focuses on the germ barrier.
