Abstract
A fluid filter includes a first filter, a second filter coaxial with the first filter, an inlet adjacent the first and second filters, a first outlet adjacent the inlet, and a second outlet at a distal end from the inlet and the first outlet. Further, the first and second filters may be housed in a unitary canister or a canister that has a canister body coupled to a removable canister cap. First and second springs urge each of the filters into sealing contact with respective gaskets at opposite ends of the device.
