Good to know- This Brita water filter jug filters out limescale, chlorine and other impurities for clearer and fresher drinks- Each Maxtra Pro filter works for 150 litres - around a month - and no worries about waste because your old cartridges are recyclable- When the cartridge needs replacing, the Brita smart light tells you when it's time to swap in a new one- You'll get 1.4 l of filtered water out of it - plenty for filling the kettle- Its slim design should fit perfectly in your fridge door, so you can get cold water right away- Keeping it in pristine condition is a breeze - just pop the jug in the dishwasher (without its lid)
