GE Under-Sink vs. Refrigerator Filtration: Choosing the Right GE System
For GE Appliances households deciding between GE GXRTDR under-sink RO ($250--$350) and relying on GE refrigerator water filter ($30--$50 every 6 months): the GXRTDR provides RO-purified water at the kitchen faucet for cooking, pot filling, and general kitchen use; the refrigerator filter provides cold filtered water from the door dispenser and ice for drinking. The optimal configuration is both: GXRTDR for cooking and tap water; refrigerator filter for cold drinking water and ice. Total annual filter maintenance cost for the combined system: $80--$130 (GXRTDR filter set) + $60--$100 (refrigerator filter x2/year) = $140--$230/year for comprehensive GE-ecosystem filtered water.
