I have a Cascade 1500 and received it as a replacement. First, there are no labels on what white hard cylinders are and no instructions. So before you put the activated carbon filter (it's black) in place, rinse it with water until it runs clear. Also, there is no information about the order in which to place the filters. So if you're new to Cascade, it's worth checking out. just tightly stuffed and had to push the baskets down.
