Abstract
A filtration arrangement includes a filtration element and a housing disposed around, and retaining the filtration element therein. The housing includes: a first and second ends and a wall portion extending therebetween. An outlet is defined in the housing proximate the first end, a primary inlet is defined in the housing proximate the second end, and a plurality of secondary inlets are defined in the wall portion. The first end of the housing is adapted for coupling to a main housing of a flow generating device encircling an air inlet thereof. The primary and secondary inlets are positioned and structured to communicate ambient air from the surrounding environment to the filtration element. the outlet is positioned and structured to communicate the ambient air that has passed through the filtration element from one or more of the primary and secondary inlets to the air inlet of the flow generating device.
