BRITA water filter products use a mixture of carbon and ion exchange resin to remove hardness, chlorine, heavy metals such as lead and copper, and other organic impurities to improve the taste, smell and appearance of cold and hot drinks. The Elemaris White water filter jug uses the BRITA Maxtra cartridge for 20% better limescale reduction. With a larger capacity ideal for families and regular use, Elemaris White features 'Memo', the electronic cartridge exchange indicator to remind users when to change the cartridge. It holds 2.2 litres filtered water, or 3.5 litres in total. It is scratch resistant and dishwasher safe (excluding lid.)
