Your 21.2 cu. ft. side-by-side Whirlpool refrigerator model no. WRS322FDAM03 uses Everydrop Filter 1 (EDR1RXD1) replacement water filter
The Whirlpool refrigerator WRS322FDAM03 water filter replacement, built with the genuine EveryDrop Filter 1 (EDR1RXD1), ensures your drinking water stays clean and fresh at any time of day. It immediately eliminates stale, metallic tastes and actively filters out heavy lead, harsh chlorine, and microscopic contaminants — keeping both water and ice quality stable with everyday use.
Backed by NSF/ANSI certification, it supports dependable contaminant reduction you can rely on. The twist-and-lock mechanism clicks the cartridge securely into place in seconds — no tools needed — preventing pressure drops and internal water leaks. Replace every 6 months or 200 gallons to maintain 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.
