LG (52)
FiltersFast published compatible-models list as crawled (complete in the returned page). Short-fat internal cartridge for older LG side-by-side refrigerators. LT500P is NOT interchangeable with LT600P — different collar/neck despite similar era and housing style (FilterCompass fit warning, consistent with the distinct part families in LG's finder chart). Genuine LG stock is intermittent per multiple sources; most units sold today are third-party.
Certification
Certified: Yes — NSF/ANSI 42 by NSF International, verified against the certifier's listings on 2026-11-11. Certifier listing (listed as: GEN11042FR-08 (system) — LT500P / LT500PC / LT500PCS)
NSF/ANSI 42 only. FiltersFast OEM specification lists NSF Certification(s): 42 and its FAQ states the LT500P is NSF/ANSI 42 certified for chlorine taste & odor and is NOT certified to reduce lead. Multiple independent listings for the genuine 5231JA2002A likewise state 'tested and Certified by NSF International against NSF/ANSI Standards 42' (96.4% chlorine taste & odor, particulates Class III). No 53 or 401 certification was found for the OEM cartridge; the FiltersFast comparison graphic showing 53 attributes for its PH21420 house brand does not transfer to the OEM cartridge. MERGE LISTING CHECK 2026-11-11: NSF's own directory (LG Electronics company listing) shows system GEN11042FR-08 covering LT500P/LT500PC/LT500PCS under NSF/ANSI 42 only (chlorine, particulate Class III, taste & odor; 500 gal, 0.5 gpm) — matching the 42-only record. No 53 listing for this system.

Aftermarket capacity note: some aftermarket manuals rate LT500P replacements at 300 gallons vs the OEM 500-gallon rating recorded here from FiltersFast's OEM specification.
