FIELD: medicine.
SUBSTANCE: group of inventions relates to medical equipment and can be used in blood treatment for removal of unfavorable components, such as aggregates and leukocytes. Filtering element for the blood treatment filter comprises a nonwoven material which has an equivalent of carboxyl groups of 20 to 140 mcEq/g and ζ-surface potential from 0 mV to 150 mV. Disclosed are a blood filter comprising a filter element and a container for accommodating a filter element, having a first and a second port as liquid inlet/outlet, and a leukocyte removal method comprising a step of passing a leukocyte-containing liquid through a blood treatment filter.
