Read guideSoftener or filter?
They solve two completely different problems
A softener protects your pipes, boiler and skin from scale. A filter changes what comes out of the tap to drink. Buying the wrong one is the most common, and most expensive, hard water mistake.
Compare the optionsWater softener
Removes the calcium and magnesium that cause scale. Protects boilers, kettles and washing machines, softer skin and hair.
Drinking filter
Improves taste and reduces chlorine, metals or specific contaminants. Does not stop scale in your hot water system.
Limescale cost
Scale can cut boiler efficiency and shorten appliance life. The real cost shows up on energy bills and replacements.
What we test
Running costs, salt or cartridge prices, install reality and whether the claims hold up in a normal UK home.
