Your 26.4-cu ft side-by-side refrigerator model No. WSF26C3EXF01 uses Everydrop Filter 1 - EDR1RXD1 water filter
Water quality doesn’t usually change all at once; it shifts gradually. The Whirlpool refrigerator WSF26C3EXF01 water filter replacement, built with the genuine EveryDrop Filter 1 (EDR1RXD1), helps keep those small changes under control. It reduces chlorine taste, sediment, and unwanted contaminants that can quietly affect how your water smells, tastes, and looks, delivering a more consistent, dependable drinking experience every day.
Backed by NSF/ANSI certification, it supports reliable filtration performance you can count on. The twist-in fit aligns easily and holds securely without leaks or tools. Replace every 6 months or 200 gallons to maintain steady water flow and prevent buildup. Follow our replacement guide to stay on schedule and get the most from every cartridge. A quick 2-gallon flush after installation clears the line and delivers clean, great-tasting water from the first pour.
Most refrigerator water filters are designed to last approximately 6 months or filter up to 200 gallons of water — whichever comes first.
Modern LG, Samsung, Whirlpool, and Frigidaire refrigerators have built-in filter indicators that notify you when it's time for a replacement.
A drop in water pressure, an unusual taste, or an off smell from your dispenser are clear signs your filter is overdue for a change.
