The pre-filter includes a filter panel having a width less than or equal to the width of the top portion and a depth less than or equal to the depth of the top portion at least during insertion of the filter panel into the frame, and height equal to or greater than the height of the air flow openings. A filter system using the pre-filter includes a tank, an air intake aperture, an air exhaust aperture, and a cartridge filter.
