What about Katadyn's Carbodyn filter? I don't think they market them in the US, and while it's not specifically designed for the Expedition filter it does have 1/4" BSP threaded output which will screw right in place of the standard 1040 filter unit. It provides ceramics to filter out the particulates and has a carbon core for getting odor/taste/chemicals out of there. Of course I'd check in with the manufacturer and run a bunch of tests on my filtered water before drinking from any chemically contaminated source.
