Claim:
1. A filter apparatus to filter air being discharged from an air duct into a space at a duct opening in a surface associated with the space, said filter apparatus comprising: a venting device having frame defining a venting area with one or more openings through which the air passes from the air duct into the space when said filter apparatus is in a closed position with a back surface of said venting device in abutting relation to the surface at the duct opening disposing a front surface of said venting device toward the space; an air filter having a filter component configured to filter the air; one or more filter brackets attached to or integral with the venting device, said one or more filter brackets being structured and arranged to position said filter component of said air filter substantially between said air duct and said venting area so as to filter the air coming from inside the air duct before the air is discharged to the space through the venting device so as to remove contaminants from the air prior to the air being discharged into the space; one or more duct brackets attached to or integral with one of the air duct and the surface at the duct opening; and a connecting mechanism interconnecting said one or more duct brackets and at least one of said venting device and said one or more filter brackets, said connecting mechanism structured and arranged to selectively allow said filter apparatus to be moved between said closed position and an open position with said venting device and said air filter in spaced apart relation with the surface and the duct opening to allow access to said air filter to inspect and/or remove said air filter from said filter brackets without requiring tools, said connecting mechanism comprising a flexible spring wire having a proximal end at one of said venting device and said one or more filter brackets and a distal end disposed through a slot at said one or more duct brackets, said flexible spring wire configured to expand and engage said slot when said venting device is pulled away from the surface so as to support said venting device in spaced apart relation to the surface when said filter apparatus is in said open position and to collapse when said venting device is pushed inward towards the surface to place said filter apparatus in said closed position.
