Abstract
A filter cartridge assembly including a replendam that combines a particulat e filter with an irregular shaped gas sorbent bed. Best operational practice requires that the air passing through the filter be distributed uniformly ov er the sorbent bed. The replendam directs the air over the surface of the large r sorbent bed utilizing vane-like structures extending from the reticulated member providing for uniform distribution.
