LG ADQ74793501 Water Filter: Complete Guide — Same as LT1000P, Explained (2025)
LG ADQ74793501 Water Filter: Complete Guide — Same as LT1000P, Explained (2025)
ADQ74793501 vs LT1000P — Complete Equivalence Proof
LG uses two parallel naming systems for every water filter it produces. The ADQ number (e.g. ADQ74793501) is the internal engineering part number — this is what appears on the filter label itself, on service documentation, and in LG’s parts database. The LT number (e.g. LT1000P) is the consumer-facing retail name printed on the box that goes on store shelves.
They are the same physical product. The ADQ number does not change between production runs. The LT number was introduced to make the consumer experience simpler. When your filter label shows ADQ74793501, you need an LT1000P. When you search for “LT1000P compatible,” any listed compatible filter also fits ADQ74793501.
The ADQ36006101/ADQ36006102 (LT700P) is the previous generation of LG filter used in 2014–2018 fridges. They look very similar, have the same form factor, but different thread dimensions — they will not lock correctly in each other’s housing. If your label shows ADQ36006101 or ADQ36006102, you need the LT700P, not the LT1000P. Detailed guide: LG LT700P / ADQ36006102 Complete Guide.

ADQ74793501 Cost-Per-Gallon Analysis
At 200 gallons rated capacity, the true cost metric for water quality is cost-per-gallon — not cost-per-filter:
| Filter Option | Price | Rated Gallons | Cost Per Gallon | Annual Cost (4 filters) |
|---|---|---|---|---|
| LG OEM LT1000P | $44.99 | 200 | $0.22 | ~$90 |
| SwapMyFilter Compatible | $19.95 | 200 | $0.10 | ~$40 |
| Bottled water (avg) | ~$1.00/gallon | — | $1.00 | ~$365+ |
At $0.10 per gallon, NSF-certified compatible filtered water from your LG refrigerator is the lowest-cost certified-quality drinking water option available. According to EPA WaterSense data, the average American uses approximately 80–100 gallons of water per day for all household purposes — making the per-gallon cost of any drinking water solution a meaningful long-term budget consideration.
Complete LG Filter Maintenance — Don’t Forget the Fresh Air Filter
While you are replacing the ADQ74793501 / LT1000P water filter, it is worth checking whether your LG refrigerator also uses an LG Fresh Air Filter (LT120F or ADQ73334008) — a small odour and bacteria filter installed in the upper interior of the refrigerator compartment, separate from the water filter. Many LG French door models (LRMVS, LRFXS, and others) include this secondary filter, which LG recommends replacing every 6 months in parallel with the water filter.
The Fresh Air Filter is a different product entirely — it filters airborne odours inside the fridge, not drinking water — but replacing both on the same schedule means only one maintenance event every 6 months rather than two. Look for a small rectangular or oval filter housing on the rear wall or ceiling of the refrigerator compartment. If your LG has one, the filter indicator panel typically shows a separate “Fresh Air” or “Air Filter” indicator that turns red when replacement is due.
