Abstract
A leukodepletion filter is provided including glass fiber filter pads and non-woven polyester fiber filter pads sealed within a filter housing. The filter is designed such that a fluid, such as whole blood, packed red blood cells, platelets or plasma, is conducted through the glass fiber filter pads before the non-woven polyester fiber filter pads. A method is further provided for leukodepleting a body fluid by filtering the body fluid through glass fiber filter pads and also filtering the body fluid through non-woven polyester fiber filter pads. After filtering, the body fluid is collected.
