Water quality doesn’t drop all at once — it fades over time. If it’s been a while since your last change, the Whirlpool refrigerator WRS555SIHZ03 water filter replacement, built with the genuine EveryDrop Filter 1 (EDR1RXD1), helps restore proper filtration. It reduces chlorine, sediment, and unwanted particles that can affect both taste and clarity — keeping your water and ice quality consistent with every use.
Backed by NSF/ANSI certification, it supports dependable contaminant reduction you can rely on. The twist-in design locks into place quickly without tools. Replace every 6 months or 200 gallons to prevent buildup and keep water flow steady. 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.
