Your Whirlpool 24 cu. ft. side-by-side refrigerator Model No. WRS315SDHM01 uses Everydrop Filter 1 - EDR1RXD1 water filter
Over time, even a working filter can lose its ability to properly clean your water. The Whirlpool refrigerator WRS315SDHM01 water filter replacement, built around the genuine EveryDrop Filter 1 (EDR1RXD1), is designed to restore that performance. It targets chlorine taste, sediment, and odor-causing elements that gradually affect how your water looks, smells, and tastes.
Backed by NSF/ANSI certification, it helps reduce key contaminants and supports safer, more consistent water quality. This replacement uses a smooth twist-in mechanism that locks into place securely without tools or adjustments. Replace every 6 months or every 200 gallons to avoid buildup and maintain steady water flow. 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.
