Overview
This is a Maxblue ADQ73613401 refrigerator water filter, sold as a pack of 3 replacements for LG LT800P and related Kenmore models. It is certified to NSF 42 and 372 standards for lead free materials and chlorine, odor and particle reduction.
As a third party alternative to the LG or Kenmore branded filter, its value case rests on compatibility and price rather than any new filtration approach. Owners across several LG and Kenmore French door refrigerators report a direct swap with the stock filter housing and no leaking, which is the main risk with aftermarket cartridges of this kind.
- NSF 42 and 372 certified for lead free materials
- Pack of 3 cartridges
- Reduces chlorine, odor and heavy metals per attribute data
- Compatible with listed LMXC, LMXS, LNXC and LSXC series LG fridges
Who it's for
This fits LG LT800P based refrigerators and the listed Kenmore models such as the 9490 and 469490 series. Check your existing cartridge or model number against the compatibility list before ordering, since fridge filter housings vary even within a brand.
What buyers say
From Amazon customer reviews.
Owners consistently describe an easy, leak free install and note the water tastes noticeably better once the filter is fully primed, with one recommending a full 10 cup flush before use. A couple mention the taste effect fades somewhat after a couple months of heavy use, though still call the price a strong value against the name brand.
Strengths and trade-offs
Drawn from this product's published specifications.
- Direct fit reported across several LG and Kenmore models
- Removes tap water taste according to multiple owners
- Lower cost per filter than the OEM 3 pack
- Needs a full flush cycle before water runs clear
- Taste effect fades somewhat after months of heavy use
Performance notes
The filter is built around standard activated carbon filtration and needs an initial flush, typically several minutes or a few gallons of water, before taste and clarity settle in, which several owners confirm matches the priming step described in the instructions. NSF 42 and 372 certification covers chlorine, odor and lead free materials rather than a wider list of contaminants.
