Creative Tools posted a nice universal filament filter:

I made the one uploaded here specifically for my Makerbot Replicator 2. The holder fits into the top of the gantry where the filament tube normally is inserted. Then the filament tube is inserted into the top of the wiper holder. Cut a piece of sponge material to fit inside the holder and poke the filament through the sponge when changing filaments.
