The short answer on the LT500P
The LT500P is the lt500p bay cartridge for lg refrigerators — it installs with no chip handshake. It has no NSF claim stated in our evidence file. LT500P replaces: Distinct slot.
Verified fit: 152 refrigerator models in our cross-checked library. Install time: 2 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.
LT500P vs LT700P vs LT800P — which cartridge does your fridge take?
| Part | Interface era | RFID chip | NSF claims | Replacement path |
|---|---|---|---|---|
| LT700P | Side-by-side LT bay | No chip | 42/53/401/372 | Distinct slot |
| LT800P | LT800P bay | No chip | Not stated in our evidence file | Distinct slot |
| LT500P | LT500P bay | No chip | Not stated in our evidence file | Distinct slot |
Certification lines above are traced to our verified evidence file (part-number × version facts); third-party compatibles usually carry less.
What an LT500P should cost
We do not print an OEM list price for the LT500P — 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 2 minutes
- Twist the old cartridge a quarter turn counterclockwise and pull it straight down — keep a towel in reach for the dribble.
- Check both o-rings sit in their grooves, then fill the new cartridge's top with cold tap water so the chamber is not fighting an air pocket.
- Offer the new cartridge to the bay, push up, and twist a quarter turn clockwise until the positive stop catches.
- Run 1–2 gallons through the dispenser to flush carbon fines, then hold the filter-reset control about 3 seconds until the status light clears.
What the LT500P 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 LT500P replace?
Replacement path: LT500P bay. 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 LT500P 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 LT500P?
A 2 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 LT500P?
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.
