Your 21 cu. ft. side-by-side refrigerator model No. WRS322FDAB00 uses Everydrop Filter 1 (EDR1RXD1) water filter
The Whirlpool refrigerator WRS322FDAB00 water filter replacement, built with the genuine EveryDrop Filter 1 (EDR1RXD1), quickly refreshes your kitchen after stagnant lines or extended periods without use. It flushes away stale odors and cloudy sediment, trapping dangerous lead, strong chlorine, and hidden impurities before they reach your glass — keeping both water and ice quality consistent every day.
Backed by NSF/ANSI certification, it supports dependable filtration you can trust. The twist-and-lock design requires no tools and creates a perfectly tight seal that prevents internal leaks. Replace every 6 months or 200 gallons to keep your home’s water tasting fresh. 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.
