Description Every water filter makes the same promise. PureFlow™ is the only one that proves it — a built-in screen shows your filter life % and water temperature in real time, powered entirely by the water flowing through it. No batteries. No plug. No guessing. Inside, an activated-carbon cartridge helps reduce chlorine taste & odour, limescale build-up and microplastics, while a self-powered UV stage adds the same type of treatment water plants have used for decades — now at your kitchen tap. Flick the lever for instant unfiltered water (washing up) and back for purified — so every cartridge lasts as long as it should.
