Claim of US Patent No. 9,878,274

1. A V-bank filter comprising:
a first side panel;
a second side panel, the first and second side panels having parallel first edges oriented perpendicular to a flow direction
through the filter; and

a plurality of filter elements arranged in pairs of vees extending between the first and second side panels, the first side
panel, second side panel, and the filter elements comprising a unitary disposable filter, wherein the plurality of filter
elements comprises:

a first filter element in a first vee pair,
a second filter element in the first vee pair, and
a third filter element in a second vee pair, wherein each of the first filter element, second filter element and third filter
element has a unique orientation direction relative to the flow direction, and

wherein the V-bank filter comprises a filter inlet located at an upstream end of each of the first and second side panels
and a filter outlet located at a downstream end of each of the first and second side panels, wherein the flow direction through
the filter inlet is substantially parallel to a flow direction through the filter outlet, and wherein the unique orientation
of the first filter element, the second filter element and the third filter element comprises:

a first orientation direction extending in the direction from the inlet to the outlet through a centerline of the first filter
element;

a second orientation direction extending in the direction from the inlet to the outlet through a centerline of the second
filter element; and

a third orientation direction extending in the direction from the inlet to the outlet through a centerline of the third filter
element, wherein none of the first orientation direction, second orientation direction or third orientation direction are
parallel.
