How often should I replace the water filter and air filter?

Both the water filter and air filter should be replaced every 6 months to ensure the highest possible water quality and optimal filtering of refrigerator odors. The Water Filter Status on the user interface prompts you to replace the filter after a standard amount of water (125 gal/453 L for PurePour™) has flowed through the system. The filter status light on the main controls also prompts you to replace the air filter after six months. (Pages 40-41)
