This smart shower head filter works wonders on London's hard water

★★★★★What we love: Aesthetically pleasing, easy to install and compatible with an iOS app that notifies users on temperature and refillsTake note: Pricey, with a limited selection of colours available, and the water pressure is not adjustable“Using a three-stage filtration with CRS and ADMS to remove limescale, metals and chlorine from the water, this smart design features a built-in intelligence system that analyses my shower habits,” Maisie explained. The shower filter is packed with smart but thoughtful features. “I love piping hot showers, but the app made me realise the temperature was too high – and the danger of scorching showers to hair and skin health,” Maisie added. “The app also tracks real water usage, the duration of the shower, skin health, carbon emissions, optimal time, the metals filtered, as well as the filter life and when to change it. Aside from the app, the shower head features a SmartHeat™ light that lights up when temperatures reach over 42°C, as well as a SmartRefill™ light to alert users to replace their filter.” Despite the initial expense, the subscription offer helps you save some pennies, too. Type: Hose shower filter Colour: Three – Brushed chrome, brushed brass and brushed bronze Easy to install: Yes
