Kenmore 9890, 46-9890 Refrigerator Water Filter

The Kenmore 9890 is one of the more straightforward filters in the lineup, but it comes with a standout specification most buyers overlook: a 500 gallon capacity. That is the highest rated capacity across all Kenmore filter models and covers roughly one year of use for most households before replacement is needed. NSF 42 certified to reduce chlorine taste and odor. The grille-mount slide-and-twist installation sits at the base of the refrigerator rather than inside the compartment, which is a different setup from most other Kenmore filter models. If the dispenser has slowed or water taste has shifted, this is the filter that needs replacing.

Why Choose the Kenmore 9890 Water Filter

The Kenmore 9890 carries NSF 42 certification, independently tested to reduce chlorine taste and odor. For households on standard municipal water where chlorine taste and odor are the primary concern, NSF 42 coverage is likely sufficient. Here is what the 46-9890 specifically addresses:

• Chlorine taste and odor
• Turbidity and particles down to 0.5 microns
• Sediment, rust, and dirt
• Odors from the water dispenser

FAQs

What makes the Kenmore 9890 different from other Kenmore filters?

Two things stand out. The 9890 carries a 500 gallon capacity, higher than any other Kenmore filter in this collection. It also mounts in the base grille at the bottom front of the refrigerator rather than inside the compartment, which is a different setup from push-in and eject-style Kenmore filters. It carries NSF 42 certification only, covering chlorine and turbidity reduction rather than the broader health and emerging contaminant coverage of NSF 53 and 401 certified models.

Is the Kenmore 9890 compatible with LG refrigerators?

Yes. The 9890 is cross-compatible with LG refrigerators using the LT500P filter. Compatible LG models include LFX25778SB, LFX25973ST, LFX25974ST, LMX25964ST, and LRSC21934SB among others. Always verify the refrigerator model number before ordering.

How does the grille-mount installation work?

Locate the filter housing at the base grille at the bottom front of the refrigerator.

Flush for 5 minutes before use and reset the indicator light if applicable.

How often should the Kenmore 9890 filter be replaced?
