Dafi's mission is to stimulate the palate with good and healthy cuisine based on fresh water and ingredients Dafi water filters are designed to provide clean and fresh drinking water. Dafi filter cartridges purifies water from lime scale, chlorine, pesticides, rust and other mechanical and organic impurities Filtering bed The secret of pure water lies with the filtering bed. The appropriate amount of ion exchange resin in the cartridge allows the capture of magnesium and calcium salts, which are compounds that cause precipitation of lime scale. This way water is softened, preventing deposition of lime scale in household appliances and cloudy sediment disappears from tea. The activated carbon contained in a cartridge absorbs all impurities and chlorine found in tap water Operation of the filter A specially designed filtering bed produces water circulation and its circular motion, thus causing longer contact of water with the filtering bed and allowing effective filtration. Similarly, the micro porous structure of the bottom of the cartridge increases the hydrostatic pressure of water and accelerates the process of purification.
