Your 28 cu. ft. side-by-side refrigerator model No. WRS588FIHZ00 uses Everydrop Filter 1 - (EDR1RXD1) water filter
You don’t usually notice your fridge filter — until the water starts tasting different or the ice isn’t as clear as before. The Whirlpool refrigerator WRS588FIHZ00 water filter replacement, built with the genuine EveryDrop Filter 1 (EDR1RXD1), helps keep that change from happening. It works quietly to reduce chlorine, sediment, and odor-causing elements that can affect water clarity and taste over time — keeping both water and ice quality stable throughout daily use.
Backed by NSF/ANSI certification, it supports reliable contaminant reduction you can count on every day. The twist-in connection aligns easily and stays secure without leaks or tools. Replace every 6 months or 200 gallons to maintain steady water flow and consistent results. 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.
