Water Filter for the LG LFX25961AL (LT600P)

LFX25961AL specifics — where the filter actually lives

Where the filter actually lives: in the fresh-food compartment, typically the upper back wall in most French-door layouts — usually a kneeling-height or shoulder-height swap, not a teardown. The seat combines push-fit and twist-lock: seat first, rotate second — reversing the order is the only way to fight this bay, and it will not let you.

Two quirks worth knowing before you order: a stubborn first twist when the old o-ring has set, and a change-filter light that will not clear itself until you hold the reset. Read the prefix and the maintenance writes itself: LG uses it across the French-door range, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts catalog. That AL suffix is trim-level shorthand. LG kept the LT600P bay common to every finish in the line.

LF vs LS — what the prefix tells you

The catalog pairs LF with LS, and the split matters at order time: Chassis first: French-door (LF) versus side-by-side (LS). The shared cartridge line covers both without adaptation. call it a 25 cu ft box — which is why this cartridge works for a living rather than sitting decorative.

Swap it in 5 minutes

• Press the release (if fitted), twist the old cartridge free, and pull it from the header.
• Wet the new cartridge’s o-ring with cold tap water so it seats without dragging.
• Push the cartridge square onto the header, then give it the locking quarter turn.
• Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.
