We recently moved into a new house, and I love the kitchen. It has a great center island with cabinets and drawers in it for storage. There are lots of other cabinets and drawers as well. The refrigerator has water and ice dispensers in the front, which makes it really nice and easy to grab a glass of water whenever I am thirsty. However, I realized I don’t know how often I need to change the filter, and there aren’t any instruction manuals here for the fridge. My fridge takes part #t2rfwg2, how often do I need to replace these?
