Abstract
A filter retention system for releasably retaining a filter cartridge in an operable position within air supply and air exhaust systems is comprised of a filter cartridge, filter retainers, mounting frame with integral sealing knife edge and filter alignment brackets. The filter retainers allow for installation and removal of the filter cartridge without the use of tools. The retention system automatically aligns filter cartridges such that an airtight seal is created between the sealant containing groove in the filter cartridge and the sealing knife edge of the retention system.
