Overview
A pack of four replacement refrigerator water filters built to fit LG's LT800P slot, covering part numbers ADQ73613401, ADQ73613408, ADQ75795104, and ADQ73613402, plus Kenmore's 9490 and 46-9490 filters. Each is NSF/ANSI 42 and 372 certified and rated for 200 gallons or about 6 months of use.
This is a compatibility part, not an appliance, so the useful question is which fridge it slots into rather than what it looks like. It's built for LG side-by-side and French door models in the LMXC, LMXS, LSXC, LSXS, and LNXC families, plus certain LPXS and LUPXC models, and it doubles as a Kenmore 9490 replacement since that model shares the same LG-built filter slot.
- Replaces LG LT800P, ADQ73613401/408, ADQ73613402, ADQ75795104
- Also fits Kenmore 9490 and 46-9490 filter slot
- NSF/ANSI 42 & 372 certified, 200 gallon / 6 month rated life
- Pack of 4 with install date stickers included
Who it's for
Owners of an LG LT800P-compatible fridge, or a Kenmore model that takes the 9490 filter, who want a multi-pack instead of paying for factory-branded filters one at a time. Not for shoppers whose fridge takes a different LG filter number or a non-LG brand, since this filter is specific to the LT800P slot.
What buyers say
From Amazon customer reviews.
Buyers who switched from LG's own factory filter say they can't tell a taste difference and appreciate the lower cost of buying four at once, with several noting easy tool-free installation and no leaking. One reviewer who compared it against a store-bought LG filter suspected the two are made in the same factory.
Strengths and trade-offs
Drawn from this product's published specifications.
- Only fits the specific LT800P-style slot, not every LG or Kenmore filter
- No visible flow indicator beyond the included install stickers
Performance notes
The carbon block inside is built to reduce chlorine taste and odor along with other contaminants covered under the NSF/ANSI 42 and 372 certifications, and each filter is rated for 200 gallons or roughly six months before it needs swapping. Install stickers are included so you can mark the date and track when a filter is due for replacement.
