Abstract
A collapsible air filter assembly for a heating and ventilation air conditioner (HVAC) system includes a filter element, and a frame supporting the filter element. The frame includes at least two edges each including a respective spring element configured to be moveable between an open state and a bent state. A compressible air filter assembly for an (HVAC) system includes a filter medium having rounded pleats configured to collapse and rebound in a controlled and repeatable manner between a compressed state and an original uncompressed state. A soft-wrapped filter assembly includes a frame in a box configuration. The frame includes rigid edges and openings to permit airflow. A filter element is encased by the frame. Flexible edge covers mounted on respective edges of the frame to provide an air seal in an HVAC system.
