ABSTRACT:
A vacuum cleaner filter assembly having a filter frame with a frame sidewall defining an enclosed perimeter. A filter is mounted in the filter frame and has a surface through which air can pass. A deodorizer chamber has a first sidewall connected to a first portion of the frame sidewall, and a second sidewall connected a second portion of the frame sidewall. The deodorizer chamber has a filter-facing portion facing a first portion of the filter, and defines a passage from there to a portion of the chamber not facing the filter. A number of deodorizer pellets are contained in the chamber. The filter assembly has parallel first and second air paths. The first path extends through the first portion of the filter and the chamber. The second path extends through a second portion of the filter that is not covered by the pellet chamber and not through the chamber.
