1. An air filter for filtering particulates from a mixture of air and particulates, the air filter comprising:
a filter housing comprising a single planar sheet of cardboard configured to be folded from a relatively flat state to a deployed state, the filter housing comprising an inlet and an outlet; and
a filter media pack disposed at least partially within the filter housing and configured to receive a mixture of air and particulates through the inlet and filter at least a portion of the particulates from the mixture of air and particulates to create filtered air directed through the outlet, at least a portion of the filter media pack extending at an oblique angle with respect to a direction extending from the inlet to the outlet, the filter media pack comprising:
a filter layer comprising one or more filter sections; and
a plurality of filter media supports disposed along the filter layer from approximately the inlet to approximately the outlet, the plurality of filter media supports being configured to support the filter layer,
wherein a first filter media support of the plurality of filter media supports is spaced a distance apart from a second filter media support of the plurality of filter media supports nearest the inlet.
