Overview
A 4-pack replacement refrigerator water filter cartridge built to fit LG's LT500P filter slot and the equivalent Kenmore 9890 / 46-9890 cartridge, carrying NSF 42 and NSF 372 certification.
This is a generic replacement part, not an LG-branded filter, using a coconut shell carbon block instead of the coal or walnut-shell media found in some cheaper filters. The listing's compatibility list is long, covering LG models like the LFX25974ST and LMX25964ST alongside Kenmore-badged equivalents, so matching your exact refrigerator model or your old filter's part number before ordering is worth the extra minute.
- 4-pack of coconut shell carbon block filters
- NSF 42 and NSF 372 certified
- Fits LG LT500P and Kenmore 9890 filter slots
- Rated for about 6 months or 300 gallons per filter
Who it's for
Fits owners of the LG LT500P-family filter slot, including the ADQ72910901/911 and 5231JA2002A/B part numbers, or Kenmore models using the 9890 / 46-9890 filter. Not for refrigerators using a different filter shape or part number.
What buyers say
From Amazon customer reviews.
Buyers who switched from OEM LG filters describe matching taste, flow rate and fit, several calling out the lower price as the main reason they switched and stuck with it over repeat orders. The only reservation raised is one reviewer not fully trusting the fridge's built-in filter reminder and tracking the change date manually instead.
