ABSTRACT:
A filter column module is disclosed, which has an upper column having a top opening, and a protruding bottom shell. The bottom shell has a plurality of apertures, and a diameter smaller than that of the upper column. A lower column has a support at the bottom and an opening that accommodates the protruding bottom shell of the upper column. The support partially contacts the protruding bottom shell of the upper column, and liquid or air can pass through the support. A filter is placed between the protruding bottom shell of the upper column and the support of the lower column.
