With BRITA every tap becomes a source of fresh tasting water that never runs out. The XXL source of pure, filtered water, ideal for families and offices. The BRITA Flow features: Innovative 4-stage filtration with natural activated carbon from coconut shells and ion exchanger pearls: filters trace impurities such as certain herbicides, pesticides and pharmaceuticals and reduces taste-impairing chlorine and metals like lead and copper. A digital indicator counts down the time of cartridge usage and flashes after 4 weeks (150 litres) to remind you to change and recycle your filter cartridge. BRITA
