Abstract
A filter for absorbing odoriferous matter from ambient air has a single body with a line of weakness that extends across at least a portion of the body and divides the filter element into at least two separately usable sub-filters. The line of weakness permits the separation of the single filter element into the sub-filters without the use of a tool. The filter element can be used in combination with varying size air purification units. The filter element can be placed in the filter housing of a large air purifier or after separation the sub-filters can be used in multiple correspondingly sized smaller air purifiers.
