Overview
This Waterdrop refrigerator water filter is built to fit LG refrigerators that use the ADQ72910901 filter, per the model naming, and is NSF 42/372 certified, sold as a single cartridge measuring 3.15 x 3.15 x 5.43 inches.
The compatibility is stated directly in the model number, ADQ72910901, LG's own part number for this filter slot, making this a like-for-like aftermarket replacement rather than a universal cartridge. Dual NSF 42/372 certification covers both taste and odor reduction and low-lead compliance.
