The quarter-turn classic, done right: the Refresh R-9010 replaces the Whirlpool 4396508 / Filter 5 cartridge for Whirlpool, KitchenAid and Kenmore side-by-side refrigerators. COMPATIBILITY - REPLACES: Whirlpool 4396508, EveryDrop Filter 5, EDR5RXD1, Kenmore 46-9010, 469010, 9010, 46-9085, Aquafresh WF285 and IcePure RFC05000A. Match the number printed on your current filter before ordering - the cartridge number, not the fridge brand, confirms the fit. CERTIFIED FILTRATION: Independently certified to NSF/ANSI 42, the activated carbon block reduces chlorine taste, odor and aesthetic impurities while preserving the beneficial minerals your body wants - calcium, magnesium, potassium and sodium. The BPA-safe housing keeps every drop clean, and the high-flow core holds steady water pressure and fast ice production. BEFORE FIRST USE: Insert the cartridge and twist until it locks fully - a complete seal prevents drips and loose fits. Flush 3-4 gallons of water (about 3 minutes) to clear loose carbon fines. A cloudy or gray first glass is completely normal for a new carbon filter and clears quickly - it is not a defect. LIFESPAN: Replace every 6 months or 300 gallons, sooner if flow slows or taste changes - water quality varies by municipality. Keep a spare on hand so your family never waits on fresh, filtered water or clean, clear ice. THE REFRESH PROMISE: Original-quality filtration for up to 50% less than name-brand cartridges, backed by responsive US-based support and a satisfaction guarantee. If it does not fit or perform, we make it right. Add the Refresh R-9010 to your cart today and taste the difference at your very next pour.
