Limescale & Hard Water Filters
Much of the UK — particularly London, the South East and East Anglia — has hard water rich in calcium and magnesium. These minerals leave limescale on taps, kettles and glassware and affect the taste of your drinking water. Our under-sink limescale filters reduce scale-causing minerals at the point of use, so every glass from your tap is clearer and kinder to your appliances.

Do you actually live in a hard water area?
Water above roughly 200 ppm calcium carbonate is classed as hard. That covers most of London, the South East, East Anglia and much of the Midlands. Tell-tale signs are a white crust inside the kettle, spotting on glassware and a film on the surface of hot drinks.
Point-of-use limescale filters treat the drinking water at your sink rather than the whole house, so they protect kettles, coffee machines and the taste of your water without the cost of a whole-house softener. Cartridges typically last around six months or 4,000 litres, shorter in the hardest regions.
