BRITA STYLE Smart Light filtration jug - for those looking for an exclusive design and ease of use. Recommended to change the water filter every 4 weeks, as it "collects and seals" all elements, accumulations and impurities that affect the taste and smell of water. SMART LIGHT filter replacement indicator, which resembles a traffic light system. Information will be provided by the color of the SMART LIGHT light (the light appears only when pouring water from the container): Green color - we drink fresh and great tasting water. Yellow color - it's time to think about changing the water filter. Red color - be sure to replace the water filter with a new one. Colored silicone cap. Filling water through this cap - convenient and fast. MAXTRA PRO MICROFLOW TECHNOLOGY - makes your water even fresher and cleaner (reduces limescale deposits, metals such as lead and copper, chloride and other substances, which affect the taste and quantity of water); The new MAXTRA PRO filter is even more sustainable - 50% made of bioplastic (produced from renewable biomass sources such as vegetable fats and oils, etc.) One of the great benefits of BRITA STYLE is that every time you use it, you'll be actively contributing to reducing plastic waste and at the same time extending life of your household appliances. Dishwasher safe, after removing the water filter and indicator. In the package you will find: BRITA filtration jug and BRITA MAXTRA PRO water filter.
