The short answer on the LT1000PC
The LT1000PC cartridge fits lg refrigerators using the push-in bay. LT1000P bay (certified variant). Replacement interval: ~200 gal / 6 months. This page lists every verified model, the honest certification picture, and what the cartridge should cost.
Verified fit: on-site model fit pages in progress for this part - meanwhile the Filter Finder lists every fridge it fits. Install time: 5 minutes, no tools. This page is part-number specific — for the model-page view (where the filter lives on your exact fridge), follow any link in the compatible-models table below. Twist-in from the ceiling on most LG side-by-sides; door-fridge bays sit top-right.

What an LT1000PC should cost
We do not print an OEM list price for the LT1000PC — our price file has no captured listing for it, and a guessed anchor is worse than none. Check the manufacturer's own parts store for the genuine price; third-party compatibles cluster at $8–15 per cartridge (mostly NSF/ANSI 42 only) with a premium 42+53 tier above them.

Swap it in 5 minutes
- Pull the old cartridge straight out of the header — expect a small spill, not a flood.
- Align the new cartridge with the keyed slot; it only goes in one orientation.
- Push the cartridge home until the retention latch clicks.
- Run 1–2 gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.
What the LT1000PC is actually certified to remove
No NSF claim stated in our evidence file. The honest framing: the two tiers that matter in compatibles are 42-only (taste, chlorine, sediment) and 42+53 (adds tested lead and cyst reduction). Claims are part-number × version facts — NSF listings update with annual re-tests, so re-check the certified-product database before relying on a claim. PFOA/PFOS reduction claims live under NSF/ANSI 53 (P473 protocol), not under 401 — a listing that says otherwise is wrong.
What does the LT1000PC replace?
Replacement path: LT1000P bay (certified variant). Within a family, buying the newer part number is always the safe choice — older cartridges often physically fit newer bays but cause no-water or error conditions.
Does the LT1000PC water filter have an RFID chip?
None. Only GE's RPWFE line carries an authentication chip; no other mainstream refrigerator cartridge on this site verifies electronically.
How hard is it to install a LT1000PC?
A 5 minutes, no-tools job: twist or push the old cartridge out, seat the new one, flush 1–2 gallons to clear carbon fines, then hold the filter reset until the light clears.
Which certification should I look for in a compatible LT1000PC?
No NSF claim stated in our evidence file. Third-party compatibles split into two tiers: NSF/ANSI 42 only (taste, chlorine, sediment) and 42 + 53 (adds tested lead and cyst reduction). If a listing does not name the standard, assume 42 only.
