Refrigerator, RO and Whole House Water Filter Cross-Reference (225 Model Numbers) with Maker Replacement Intervals (H2O Buddy)

Which replacement water filter fits your fridge or water system? This dataset maps 225 model and filter numbers from 14 brands (Whirlpool, Amana, KitchenAid, GE, Kenmore, Samsung, LG, Maytag, Waterdrop and more) to the compatible filters that fit them: 161 refrigerator numbers, 43 RO system models, plus whole house, pitcher and faucet filters. Each row lists the numbers that also fit, the stated change interval, rated capacity in gallons and the certification exactly as the filter maker states it, with a link to the source page in the H2O Buddy filter finder at https://h2obuddy.com. A second table gives one row per model and compatible item (294 rows, 119 SKUs). A third table lists 27 filter change intervals published by Brita, ZeroWater, PUR, Waterdrop, Whirlpool, Hisense, InSinkErator, Pentek and Kinetico, taken from https://h2obuddy.com/guides/how-often-to-change-your-water-filter.
