A fluid routing system for use in a fluid line is set forth which includes a fluid routing mechanism having a housing and a block, and a removable treatment device. The housing has an internal chamber, an inlet port for attaching to one part of a fluid line, an outlet port for attaching to another part of the fluid line, an inlet channel connecting the inlet port to the internal chamber, and an outlet channel connecting the internal chamber to the outlet port. The block is capable of movement between a first and second position and is disposed within the internal chamber of the housing. The block has a first internal cavity, a second internal cavity, an exterior surface, an inlet passageway connecting the first internal cavity with the exterior surface, and an outlet passageway connecting the second internal cavity with the exterior surface. The inlet passageway and the outlet passageway are configured to retain fluid therein when the treatment device is removed. In the first position, the inlet passageway of the block is aligned with the inlet channel of the housing and the outlet passageway of the block is aligned with the outlet channel of the housing for permitting flow of the fluid into the treatment device. In the second position, the inlet passageway of the block is misaligned with the inlet channel of the housing and the outlet passageway of the block is misaligned with the outlet channel of the housing for prohibiting flow of the fluid into the block.

A refrigerator has fresh food and freezer compartments, and each of the fresh food and freezer compartments has upper and lower portions. A first air duct extends from the upper portion of the freezer compartment to the upper portion of the fresh food compartment, and a second air duct extends between the lower portion of the freezer compartment and the lower portion of the fresh food compartment. A first fan is arranged to draw first air through the first air duct from the upper portion of the freezer compartment and to discharge the first air into the upper portion of the fresh food compartment. A second fan is arranged to draw second air from the lower portion of freezer compartment and to discharge the second air into the upper portion of the freezer compartment.
