Abstract

A filtration system that rotates in conjunction with a blower wheel (40), and a method of attaching the same. The blower wheel (40) typically has a plurality of fan blades (46) arranged in a spaced relationship radially around a blower cavity to define a flow path extending radially outward from the blower cavity through the fan blades (46) when the blower wheel (40) is rotating. The filtration system includes a filter cartridge (20, 20') releasably attachable to the blower wheel (40) in an engaged configuration. The filter cartridge (20, 20') includes a filter medium (62) defining a generally center opening and a filter surface configured to be positioned generally adjacent to the fan blades (46) and to extend across at least a portion of the flow path. In one embodiment, a plurality of flow passages extending through the filter medium.
