The Fito Filter K11 PH+ is a replacement water filter cartridge designed to provide clean and mineralized drinking water. It utilizes a combination of coconut activated coal treated with silver and ion-exchange resin to remove active chlorine, organic pollutants, and toxic metal ions, while the silver treatment helps prevent bacterial growth within the filter. This model is compatible with several systems, including Fito Filter, New Water, Cistaia Line, Aquaphor A15, and older Brita Classic models. Beyond basic purification, the cartridge features a patented mineralizer with PHYTO MIX, which saturates the water with magnesium and increases the pH and ORP levels. Depending on the size of your household, the filter lasts between 30 and 60 days, with a total filtering capacity of up to 300 litres and a maximum service life of three months from the first use. It is a practical choice for those who want to reduce water hardness and improve the overall mineral composition of their tap water for daily consumption.
