Filtered water is why you paid extra for the fridge. Six months in, the cartridge holding the chlorine back is full, the light comes on, and the guessing starts. COMPATIBILITY — REPLACES: 4396508, EveryDrop Filter 5, Kenmore 46-9010, 4396510, 4392857, NLC240V, 4396547, 46-9085, PNL240V. Fits Whirlpool, Kenmore, KitchenAid and Maytag refrigerators built on this cartridge. Match the number printed on the filter you are removing — the cartridge number confirms the fit, the badge on the door does not. PLEASE NOTE: this filter does NOT fit EveryDrop Filter 4 / UKF8001, EveryDrop Filter 1, 3 or A, W10295370A, any Samsung, LG or Frigidaire cartridge. If your old cartridge reads one of those, this is the wrong page. WHAT IT DOES: A coconut-shell activated carbon block tested to NSF/ANSI 42 reduces chlorine taste, odor and sediment, while calcium, magnesium and potassium stay in the water. BPA-free food-grade housing and a high-flow core that holds dispenser pressure and ice output. BEFORE FIRST USE: Twist the cartridge in until it locks — a complete seal is what stops drips. Flush three to four gallons, about three minutes, and discard the first ice. Cloudy first water is harmless carbon dust and clears in seconds. It is not a defect. LIFESPAN: Six months or 300 gallons, whichever comes first — and sooner if your water carries more sediment. If flow slows or the taste changes early, replace it. That is the filter working, not failing. Three cartridges here — eighteen months of scheduled changes in one order. THE REFRESH PROMISE: R-9010 from a US-based company with US-based support.
