Abstract
A filter shaking arrangement includes a resilient frame disposed around an expandable filter, both of which are expanded by a fan induced air flow. The resilient frame returns resiliently to its original form upon the cessation of this air flow. This contraction of the resilient frame tends to dislodge dirt adhering to the filter as it also is forced back to its original shape.
