1. A filter assembly for securing to an angled intake associated with a heat exchanger unit having coil arrays associated with the heat exchanger openings, said filter assembly comprising:
a multi-sided assemblable frame including individual frame components, each of said frame components exhibiting a thin planar cross section;
a multi-sided track including individual track sections secured to each of said frame components, said track sections each including an open facing slot within which are supported a plurality of screen fasteners including any of twist or toggle portions;
apertures formed through edge proximate locations of each of said frame components and which, upon overlapping alignment, receiving additional fasteners for assembling said frame so that said track sections are interconnected to define a closed perimeter;
a screen approximating in dimension an outline of said assembled track, said screen including a reinforced edge within which is configured a plurality of spaced apart grommets aligning with and receiving therethrough said twist or toggle portions of said adjustable screen fasteners extending through said slots of said interconnecting track sections in order to secure said screen to said track and frame; and
upon positioning said thin planar frame with said attached screen against a perimeter defined outer flange surface surrounding the angled coil opening of the unit, a plurality of clips adapted to engage aligning edges of said assembled frame to the flange surface in order to secure said frame, track and screen in place over the heat exchanger opening, without the requirement of conventional screw fasteners, thereby avoiding risk of puncturing the coil arrays.
