  • Method and apparatus for applying air filters
    Patent number: 8715383
    Abstract: A filter clip for holding a filter media over a supply/return/exhaust of an HVAC system includes a hook portion that secures to a grid of a suspended ceiling system and a filter holding portion that is connected to the hook portion such that the filter holding portion is biased towards the grid and/or a grille. An air filter placed between the filter holding portion and the grid and/or grille is held against the grid and/or grill until, for example, until construction is complete or the filter needs to be changed or removed, thereby covering the supply/return and reducing contamination of the HVAC system from construction dirt/debris.
