Abstract
Disclosed are filtering cartridge and methods of producing the filtering cartridge for purifying drinking water and other liquids for household, medical and other purposes. A filter cartridge is filled with a filtering material and is configured in the form of an open bowl which can be closed with a lid, having side walls and a bottom with at least one outlet opening which is closed with a water-permeable material, wherein the cartridge bottom is designed such as to make it possible to use the water-permeable material which comes to the external edge of the side walls and is made of fibers with a sufficiently small diameter to allow using the filtering material containing powder particles; furthermore, the entire area between external and internal edges of the walls along the perimeter of the bottom is made of a composite based on a polymer water-permeable material.
