    Abstract: An upright surface cleaning apparatus comprises an upper section moveably mounted to the surface cleaning head between a floor cleaning position, in which the upright surface cleaning apparatus is useable for cleaning a floor, and a storage position. The storage position includes a storage orientation of the upper section relative to the surface cleaning head wherein the upper section is stable in the storage position. The upright surface cleaning apparatus further comprises an anti-rotation locking mechanism that automatically engages when the upper section is moved into the storage position and inhibits changes in orientation of the upper section once the upper section is in the storage position. The upright surface cleaning apparatus further comprises a cleaning unit that is removably mounted to the upper section and is removable while the upper section is in the storage position.

    Abstract: An HVAC system that utilizes an air-to-air heat exchanger includes an HVAC ductwork section including a fan, and a filter assembly in fluid flow communication with the HVAC ductwork section. The filter assembly has a filter compartment having an opening oriented generally transverse to a direction of air flow through the filter assembly. A compressive member is provided on at least a portion of a perimeter extending around the opening. The compressive member is adjustable between an installation configuration in which the compressive member is spaced from a position that is to be occupied by a filter when the filter is installed in the filter compartment and an installed configuration in which the compressive member engages at least a portion of one of an upstream and a downstream face of the filter when the filter is positioned in the filter compartment.
