Frequently Asked Questions

What refrigerators use the LT1000P water filter?

The LT1000P water filter is used in select refrigerators manufactured by LG and Kenmore. These brands use several internal part numbers to reference the same filter style, including MDJ64844601, ADQ74793501, ADQ74793502, and 46-9980, along with additional cross-reference numbers listed on this page. If your refrigerator requires any of these part numbers, or one of the 30+ compatible alternatives in our cross-compatibility list, it is designed to accept the LT1000P-style filter. This filter typically installs either in the refrigerator door or at the top of the fresh-food compartment, depending on the model.

How often should I replace the LT1000P filter?

All LT1000P-compatible filters sold on this page are designed to be replaced every six months. This replacement schedule appears consistently across the factory-original LG filter and all approved compatible options such as ClearChoice and EcoAqua. Replacing the filter at 6-month intervals supports consistent water flow and helps maintain the reduction of chlorine taste, odor, sediment, rust, and other particulates. If your household uses a large amount of water or you notice taste or flow changes sooner, replacing the filter earlier may improve performance.

Do you offer OEM and compatible versions?

Yes. We offer both the factory-original LG MDJ64844601 refrigerator filter and high-quality compatible alternatives such as ClearChoice CLCH130 and EcoAqua EFF-6046A. All options are designed to fit the same LT1000P housing and reduce the same core contaminants, including chlorine taste and odor, sediment, sand, and rust. The comparison chart on this page clearly shows the features, certifications, and specifications of each option so you can choose the filter that best suits your preferences.
