Your 21 cu. ft. side-by-side refrigerator model No. WRS322FDAB01 uses Everydrop Filter 1 (EDR1RXD1) water filter
The Whirlpool refrigerator WRS322FDAB01 water filter replacement, built with the genuine EveryDrop Filter 1 (EDR1RXD1), ensures that when you test the dispenser, you’re met with crystal-clear ice and perfectly odor-free water. It aggressively traps lead, harsh chlorine, and invisible impurities — keeping both water and ice quality consistent with everyday use.
Backed by NSF/ANSI certification, it supports dependable filtration you can trust. The tool-free twist-and-lock housing secures tightly in under a minute, creating a leak-proof seal. Replace every 6 months or 200 gallons to maintain pristine 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.
