titleOfInvention	Well filter
abstract	FIELD: water supply and drainage for equipment of water intake parts of wells in non-corrosive and corrosive media. SUBSTANCE: rectangular slits expanding inwards are cut in "bridges". Length of slits equals that of " bridges". Width of slits equals height of holes under "bridges". Holes under "bridges" and rectangular slits in these "bridges" form filtering surface of well filter. EFFECT: increased porosity of filter structures, reduced hydraulic losses in filters, prolonged service life of wells, diminished usage of materials for manufacture of filter structures.
