Your 21.2 cu. ft. side-by-side Whirlpool refrigerator model no. WRS322FDAM04 uses Everydrop Filter 1 (EDR1RXD1) replacement water filter
The Whirlpool refrigerator WRS322FDAM04 water filter replacement, built with the genuine EveryDrop Filter 1 (EDR1RXD1), offers model-specific filtration for your drinking-water dispenser and ice maker. It uses activated carbon to reduce chlorine taste and odor, lead, microplastics, selected VOCs, and other impurities that can quietly affect how your water tastes, smells, and looks.
Backed by NSF/ANSI certification to Standards 42, 53, and 401, it supports dependable contaminant reduction you can rely on. The direct-fit cartridge enables easy, tool-free installation without adapters or plumbing modifications. Replace every 6 months or 200 gallons to maintain consistent dispenser flow and reliable filtration. 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.
