LFX31995ST specifics — where the filter actually lives

On the LFX31995ST, the cartridge in the fresh-food compartment, typically the upper back wall in most French-door layouts, so expect to clear one shelf edge before you have working room. Mechanically the LFX31995ST uses a push-and-twist cartridge: two motions and a flush — the entire service procedure for this bay design.

The recurring owner notes: the change light ignores the new cartridge until you reset it, and the first removal always takes more muscle than the manual implies. One prefix, one chassis family: LG built these as French-door machines, and the filter bay inherits the geometry that implies, including where the dispenser feed runs. That ST suffix is trim-level shorthand. LG kept the LT700P 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: LF covers French-door, while LS covers side-by-side. The cartridge line is usually shared across both — order by chassis, not by door count. The digits in the model number read as cabinet capacity (31 cubic feet), a decent proxy for how hard the filter works in daily service.

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.

LFX31995ST filter questions

LG LFX31995ST: how do I clear the change-filter light?

With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the LFX31995ST manual’s filter section has the exact control for your trim.

Does the LG LFX31995ST need a bypass plug when the filter is out?

No bypass needed: the LT700P bay closes on its own, and running empty simply means the water skips filtration until you seat a new cartridge.

Are off-brand filters safe for a LG refrigerator?

Certified aftermarket cartridges are built to the same NSF test standards as the OEM part, and federal warranty law (Magnuson-Moss) protects your coverage when you use them.

Why is the OEM LT700P cartridge so much more expensive?

Part of the OEM price is the badge and the distribution chain. Certified alternatives meet the same test standards at a lower unit price, especially in multi-packs.

How often should I replace the filter in my LFX31995ST?

Every six months or at the rated gallon capacity, whichever comes first — the LT700P class cartridges all share that service interval.

Do I need to turn off the water supply to change it?

No — the bay is designed for a live swap. Expect a small dribble, keep a towel in reach, and flush a couple of gallons through the new cartridge before the first glass.
