Filter with interconnected hollow elements and method of use

A filter comprising:

• (a) at least one filter arm comprising a plurality of hollow elements in fluid communication with each other, the hollow elements having porous walls, the at least one filter arm having a first end and a second end;
• (b) a hollow transition element comprising a collector having a porous side wall, a central cavity, an upper closed end and a lower open end;
• and at least one hollow transition element arm having a first transition arm end, a second transition arm end, and a porous side wall;
• wherein the first transition arm end is connected to, and in fluid communication with, the second end of the at least one filter arm;
• and the second transition arm is connected to the side wall of the collector, and is in fluid communication with the central cavity of the collector via at least one aperture in the side wall of the collector;
• and,
• (c) a hollow base having a side wall, and a base outlet port, wherein the hollow base is connected to, and in fluid communication with, the collector of the hollow transition element.
