Abstract: A filter system comprises an expandable filter with a first end of the filter attached to an end of a first tube and a second end of the filter attached to an end of a second tube. The tubes are arranged telescopically with respect to each other such that telescopic movement of the first and second tubes with respect to each other causes the filter to move between a first collapsed position and a second expanded position where the filter extends outwardly. The filter may be a folded over member when in the expanded position or a spiraling member.
