AIR FILTER
First Claim
Patent Images
1. An HVAC filter which is generally planar along an X-Y plane, the filter comprising:
- filtration media;
a rectilinear frame holding said filter media, said frame having a thickness in a Z-axis direction being normal to the X-Y plane;
wherein said rectilinear frame has two minor peripheral walls and two major peripheral walls;
wherein said two minor peripheral walls are generally parallel to each other in said X-Y plane, and extend in said Z-axis direction generally less than said frame thickness;
wherein said two major peripheral walls are generally parallel to each other, are generally perpendicular to said minor peripheral walls, and wherein at least a portion of said major peripheral walls extend in said Z-axis direction the same as said frame thickness.

15. An HVAC filter which is generally planar along an X-Y plane, the filter comprising:
-
a rectilinear frame around a perimeter of the filter, said rectilinear frame comprising a top portion and a bottom portion, said top portion nested within and affixed to said bottom portion said frame having a thickness in a Z-axis direction being normal to the X-Y plane; and
,filtration media within said frame; wherein said top portion includes a first portion that lies in a plane parallel to the X-Y plane; wherein said bottom portion includes a second portion that lies in a plane parallel to the X-Y plane and includes a pair of opposed bottom folded segments, each of said bottom folded segments having a first fold portion and a second fold portion, said first fold portions foldably attached to said bottom portion and said second fold portions, said first fold portions having a top edge and a bottom edge, said top edge being displaced from said bottom edge along the Z-axis, said second fold portion is generally planar along the X-Y plane. - View Dependent Claims (16, 17, 18, 19)
