Abstract: A sound dampening apparatus and associated methods of use are disclosed for dampening or otherwise preventing impact noises between an HVAC air filter and a cavity of an air duct in which the air filter is positioned. In at least one embodiment, the apparatus provides a base portion engagable with a lower end of the cavity. An opposing support portion of the apparatus is configured for selectively contacting a lower face of the air filter and supporting the air filter thereon. An at least one selectively compressible spring member extends between and interconnects the base portion and the support portion. Thus, with the air filter positioned between the support portion and an upper end of the cavity, and air flowing through the cavity in a substantially upward direction, the support portion prevents the air filter from impacting the lower end of the cavity upon cessation of said air flow.
