1. An HVAC system utilizing an air-to-air heat exchanger comprising:

  • a) an HVAC ductwork section including a fan;

    b) a filter assembly in fluid flow communication with the HVAC ductwork section, the filter assembly comprising a compressive member and a filter compartment for removably receiving a filter, the filter compartment comprising a flow path oriented generally transverse to a direction of air flow through the filter assembly and the compressive member wherein when the filter is positioned in the filter compartment, the filter is positioned in the flow path, wherein 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 the 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.
