Abstract
A filtering straw for drawing liquid from a container includes a tube with a pair of filters, one filter being removably mounted in each end of the tube. Each of the filters includes a portion extending into the corresponding end of the tube, each of which has an outer circumferential liquid permeable surface cooperating with the inner circumferential of surface of the tube to define an annular chamber therebetween. Accordingly, the cross sectional area through which fluid is drawn by sucking on the straw is the circumferential surface of each filter.
