The BRITA Marella Water Filter Jug includes a MAXTRA PRO All-in-One filter, which helps to give you 150 litres of fresh, filtered water in four weeks with just one cartridge. It helps to reduce chlorine, limescale, and impurities from tap water. The water jug fits in standard fridge doors and is BPA-free and dishwasher-safe (except for the digital indicator). The BRITA Marella is great for the environment as well as good for you. It can help you save hundreds of plastic bottles with a carbon footprint up to 25 times smaller than bottled water.
