Why this model does not need a water filter
LG's official specification sheet lists LRFCS25D3S as a 25.2-cubic-foot, 33-inch French-door refrigerator with a factory-installed ice maker, no ice or water dispenser, and no water filter. The ice maker uses the household water connection without a built-in replacement cartridge.
A refrigerator can use a household water connection for an ice maker without containing a replaceable filtration cartridge. Confirm that an actual filter housing exists before buying a cartridge.
