Kenmore 9990, 46-9990 Refrigerator Water Filter Replacement
Water dispenser running slower than it used to, or ice tasting a little flat? On a Kenmore that uses the 9990, that's almost always the filter talking, not the fridge itself. This one has a slide-and-twist design that's a bit different from most of Kenmore's other codes, so it's worth confirming before you order.
Confirm You Need the 9990
| Part Number | Also Known As | Install Type | Best For |
|---|---|---|---|
| 9990, 46-9990 | LT600P, 5231JA2006A, 1266885, AP4457353 | Slide-and-twist | Kenmore side-by-side, bottom-freezer, top-freezer, and select LG models |
| 9081, 46-9081 | — | Eject-and-slide | Standard Kenmore side-by-side, bottom, and top freezer models |
| 9082, 46-9082 | EDR2RXD1, W10413645A | Twist-out tray | Kenmore and Kenmore Elite bottom-freezer models |
If your old filter slides straight out toward you rather than ejecting or requiring a tray, the 9990 is likely your match.
Compatible Refrigerator Models
Like a few other Kenmore codes, this one crosses brands:
- Kenmore side-by-side refrigerators
- Kenmore bottom-freezer refrigerators
- Kenmore top-freezer refrigerators
- Select LG-manufactured Kenmore models using the LT600P filter
Always confirm your model number before ordering. This list is representative, not exhaustive, across the full compatible range.
How This Filter Actually Helps
The 9990 is NSF 42 and 53 certified, which covers both the aesthetic side of water quality, chlorine taste and odor, and the health side, reducing lead along with cysts like Cryptosporidium and Giardia that can show up in municipal or well water supplies. It's rated to filter Class I particulates down to 0.5 microns, catching sediment and rust fine enough that it would otherwise pass straight through a lower-grade filter. What it doesn't carry is NSF 401, so if you're specifically concerned about pharmaceuticals or other emerging compounds, the 9082 covers that ground and this one doesn't.
Kenmore 9990 vs 9082: Standard Coverage vs Extended Coverage
| Kenmore 9990 | Kenmore 9082 | |
|---|---|---|
| Install Type | Slide-and-twist | Twist-out tray |
| Certification | NSF 42 and 53 | NSF 42, 53, and 401 |
| Filter Capacity | 300 gallons | 200 gallons |
| Cross-Compatible | LG LT600P | Jenn-Air, KitchenAid, Whirlpool via EDR2RXD1 |
| Best For | Standard Kenmore side-by-side and freezer models | Bottom-freezer models needing broader contaminant coverage |
How Do I Check My Part Number?
Slide-and-twist is the giveaway here, if your filter comes straight out with a pull and locks in with a twist rather than an eject button or a tray release, you're likely holding a 9990. Confirm on the label directly, and if it reads LT600P or one of the several LG-manufactured codes like 5231JA2006A instead, that's still the same filter, just under a different brand's numbering.
What Happens If I Order the Wrong One?
Because the slide-and-twist mechanism is mechanically distinct from Kenmore's eject-and-slide or tray-based filters, a mismatched filter generally won't lock into place at all rather than seating loosely. That's actually useful, it means you'll know almost immediately if you've got the wrong one instead of discovering a slow leak weeks later.
How Often Should You Replace This Filter?
Replace the 9990 every 6 months or 300 gallons, whichever comes first. Heavier-use households, especially ones running the ice maker often, tend to hit the gallon cap before the six month mark rolls around, so don't rely on the calendar alone if your dispenser sees a lot of daily use.
What Customers Say

"Slide-and-twist is honestly easier than the eject style my old fridge had."
"Noticed the difference in taste within the first glass after installing."

FAQs
Is the 9990 the same filter as the LG LT600P?
Yes, functionally. The 9990 is compatible with select LG-manufactured Kenmore refrigerators using the LT600P filter, so either part number points to the same replacement.
Why doesn't the 9990 carry NSF 401 certification like the 9082?
They're built to different coverage levels. The 9990 focuses on NSF 42 and 53, chlorine, lead, and cyst reduction, while the 9082 adds NSF 401 for a broader range of emerging contaminants. Choose based on what your household's water quality concerns actually are.
How do I know if my filter housing takes a slide-and-twist filter?
If your current filter comes out with a straight pull rather than an eject button or a lowered tray, and locks back in with a clockwise twist, that's the slide-and-twist design the 9990 uses.
What if my old filter shows a code like 5231JA2005A instead of 9990?
That's expected. Several LG-manufactured part numbers, including 5231JA2005A, 1268489, and AP4457353, all cross-reference to this same filter.
Can I buy this filter in a multi-pack?
This specific listing is a single pack. Given the 300 gallon capacity, most households get roughly six months of use before needing to reorder.
