Patent ID: 8529675

Claim:
An air filter system comprising a housing, an air filter element having an inflow face and an outflow face, said filter element comprising alternating flat and pleated layers which form channels, and said channels being alternately sealed at the inflow and outflow faces such that as air to be filtered flows from the inflow face to the outflow face, the air must pass through one of the layers, a hydrocarbon vapor adsorber element having an inflow face and an axially opposing outflow face and comprising a wound cellulose carrier coated folded and formed into a honeycomb shaped axial flow element with activated carbon adhesively bound to air flow channels therein and disposed adjacent said air filter element, said inflow face of said adsorber separated axially from and facing said outflow face of said air filter element, wherein the adsorber element airflow channels substantially match a configuration of channels of the air filter element, the adsorber element airflow channels being substantially aligned with the air filter element channels, wherein said housing is a common housing to both said hydrocarbon vapor adsorber element and said air filter element, wherein the air filter element and the adsorber element are disposed within said common housing with said adsorber element airflow channels substantially aligned with said air filter element channels, a first seal member disposed on a circumferential outer surface of said air filter element, said first seal member sealing said air filter element against an interior surface of said common housing, and a second seal member disposed on a circumferential outer surface of said adsorber element, said second seal member sealing said adsorber element against said interior housing surface sealed by said first seal member.
