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, so you can keep the refreshment flowing for around a month- When the cartridge needs replacing, the Brita Memo tells you when it's time to swap in a new one- You'll get 2 l of filtered water out of it - plenty for filling the kettle and serving tea to a big group- No worries about waste because your old cartridges are fully recyclable- Keeping it in pristine condition is a breeze - just pop the jug in the dishwasher (without its lid)
