Exact fit — all 36 verified models
Harvested from published manufacturer and retailer fit lists (sources at the bottom of this page). If your exact model is not listed, do not assume fit — check the number on your current part.
Kenmore (2)
LG (34)
Curated base-model list merged from FiltersFast's published compatible-models list (very long, with many suffix/revision variants — deduplicated here), LG Australia's manufacturer fit list (GF-/SG- models) and the Woot/LG retail list (LMXS30796S, LMXS30796D, LMXC23796S, LFXC24796D, LFXS28566S, LFCS28768S, LMXS28626S, LSXS26396S). Kenmore models use the same cartridge as 46-9980; two Kenmore examples from the FiltersFast list are included and the full Kenmore run is in that source. List is representative, not exhaustive.
Certification
Maker claims NSF/ANSI 42, NSF/ANSI 53, NSF/ANSI 401 — no independent certifier listing was found when checked on 2026-11-11. Treat the claim as unverified.
Verified against LG's own performance data sheet / water filter guide (lg.com PDF): 'Tested and certified by NSF International against NSF/ANSI Standards 42, 53 and 401 in System Model MDJ64844601' — 42: chlorine, taste & odor, particulate Class I; 53: 2,4-D, asbestos, atrazine, benzene, carbofuran, cyst, lead, lindane, mercury, p-dichlorobenzene, toxaphene; plus 401 emerging compounds and NSF/ANSI/CAN 372. LG product pages state the same and link to the NSF listings at info.nsf.org. FiltersFast's specification block lists only 42 and 53 — the manufacturer's data sheet (42/53/401) governs. MERGE LISTING CHECK 2026-11-11: under the certifier-listing rule this is recorded as manufacturer-claimed — LG's performance data sheet (a manufacturer document) states NSF certification for system MDJ64844601, but no entry for LT1000P/MDJ64844601 was found in the NSF directory excerpts checked (LG's directory listing shows its LT500P/LT600P/LT800P systems). The claim may well be real; it is labeled claimed until the listing itself is produced.

LG.com US did not publish a plain single-filter price on the pages read (only bundles with the LT120F air filter at $69.99 and the $43.49 cleaning-kit SKU LT1000PB), so the headline OEM price is FiltersFast's. DiscountFilters OEM single ($74.95) clears its $70 free-shipping threshold, giving an honest shipped total of $74.95.
