Abstract
A filter apparatus for filtering chemical gases and odors from a fluid is disclosed. The filter apparatus includes a plurality of filter cartridges which each include a filter material, and a housing which fixes the filter cartridges relative to each other such that the filter cartridges form a W-shape with each filter cartridge forming a leg of the W-shape, to maximize the filtering efficiency of the filter apparatus while minimizing the pressure drop across the filter apparatus. A table top air cleaner is also disclosed,and includes a housing having an inlet opening and an outlet opening, an arrangement for drawing air through the inlet opening and for forcing air out of the outlet opening, and a plurality of filter cartridges which each include a filter material and which are fixed inside the housing relative to each other such that they form a W-shape.
