Abstract

A filter assembly has a housing defining an inlet and an outlet. A plurality of chemical filter elements are disposed in the housing and are arranged in a series with respect to fluid flow. A spacing region is between adjacent filter elements in the series. Also disclosed is an assembly having a housing and a first and second chemical filter element. The second chemical filter element is downstream of the first chemical filter element. Each chemical filter element has a sheet of chemical filter material having a first edge and a second edge. A first flow path is defined parallel to a surface of the first sheet extending from its first edge to its second edge. A second flow path is defined parallel to a surface of the second sheet extending from its first edge to its second edge.
