When to Replace Your Water Filter

Every 6 Months or 200 Gallons

Most refrigerator water filters are designed to last approximately 6 months or filter up to 200 gallons of water — whichever comes first.

When Your Fridge Displays a Filter Alert

Modern LG, Samsung, Whirlpool, and Frigidaire refrigerators have built-in filter indicators that notify you when it's time for a replacement.

Changes in Taste, Odor, or Flow

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.
