Water filter for purifying non-purified water by utilizing magnetic field

The invention discloses a water filter for purifying non-purified water by using a magnetic field. The water filter comprises a water filtering chamber, the water filtering chamber is provided with awater inlet end, a sewage outlet end and a purified water outlet end, the periphery of the water inlet end is provided with a magnet structure, and the magnetic field generated by the magnet structureenables pollutants in a water fluid to be gathered to form a pollutant group; and a filtering structure is arranged in the water filtering chamber, a central chamber respectively communicated with the water inlet end and the sewage outlet end is formed in the filtering structure, a purified water cavity communicated with the purified water outlet end is formed between the outer wall of the filtering structure and the inner wall of the water filtering chamber, and a filter element structure isolates the pollutant group in water fluid in the central chamber and filters purified water out of thepurified water chamber.
