Water Filter for the LG LFX25950TT (LT600P)

LFX25950TT specifics — where the filter actually lives

Where the filter actually lives: inside the fresh-food cavity, upper zone in most French-door builds, a deliberate placement that keeps the swap away from the door seals and drawer rails. Mechanically it is a push-and-twist seat: the keyed entry means no cross-threading, and the locking turn is short enough to do one-handed.

The small print owners learn the hard way: plan on a towel for the first pull — sitting water in the line — and a five-second reset hold once the fresh cartridge is in. The badge reads LFX25950TT, but the chassis reads LF: LF machines come from the French-door program, and LG’s parts system rewards you for knowing it: one cartridge family covers the run. Finish codes such as TT change the look, not the plumbing — order the cartridge by model, ignore the finish letter.

LF vs LS — what the prefix tells you

The catalog pairs LF with LS, and the split matters at order time: French-door against side-by-side, respectively. Filter bays rarely care — the media family carries over more often than not. capacity 25 cubic feet: a mid-to-full-size cabinet whose dispenser traffic sets the realistic change cadence.

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.
