Surely every home has a water jug waiting in the fridge? I wouldn't be without mine (or my water fountain, total game changer!) It makes sense then, that Brita water filters are a top seller in the Home & Kitchen category. They’re compatible with all Brita jugs, they permanently absorb lead and copper and reduce limescale, and get this - they make your tea taste better! No, really - they’re recommended by the UK Tea Academy and by consumers - 96% agree tea is more brilliant with MAXTRA+ filtered water.
