Improve your fridge's water quality with the Whirlpool refrigerator WRS315SDHZ water filter replacement, designed for families who want fresh, reliable hydration every day. Powered by the genuine EveryDrop Filter 1 (EDR1RXD1), it helps reduce chlorine taste, sediment, and harmful contaminants that can affect water safety and flavor. The result is cleaner water, clearer ice, and a crisp taste you can trust.
Backed by NSF/ANSI certification, it supports safe, consistent filtration for your home. This replacement installs easily with a secure twist-in design that fits tightly without leaks or tools. Replace every 6 months or 200 gallons to maintain steady water flow and peak performance. 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.
