Cartridge identity and replacement notes
Manufacturer reference: LT900X3. Documented market: US.
- Use the exact refrigerator model and cartridge family. The LG LT families are separate filter designs.
- One LT900X3 bundle has three different filtration stages: pre-carbon, UF and post-carbon. It is not a pack of three interchangeable cartridges. Exact appliance compatibility remains unverified here.
- LG's US listing provides an Inquiry to Buy action for LT900X3. Ask LG to confirm the complete bundle, availability and your refrigerator model before ordering; the individual product page is currently unavailable. An Amazon reference search is not a confirmed product offer.
- An ADQ73753313 assembly listing does not establish that it is the complete LT900X3 bundle with all three filtration stages.
