The Fito Filter Perla Si+ is a white water filter pitcher designed for kitchen use to provide a steady supply of purified cold water. It features a 3-liter capacity and utilizes the K-11 Si+ cartridge, which combines activated carbon and ion exchange resin to soften the water and remove chlorine, pesticides, petroleum products, and dissolved gases. Beyond basic filtration, the system includes a Si+ mineralizer that helps eliminate pathogens and chemical compounds through its antibacterial properties. This makes it a practical choice for those looking to improve their drinking water quality by removing chlorinated organic compounds and other impurities from the tap.
