Setup, Compatibility & Care
To install the filter, locate the filter housing in your refrigerator—typically found in the upper right corner or the base grille. Rotate the old filter counter-clockwise to remove it, then insert the new EFF-6011A by turning it clockwise until it locks firmly into place. This filter is compatible with several models including DA29-00003A, HAFCU1/XAA, and WSS-1. To maintain performance, replace the filter every 6 months or sooner if the flow rate noticeably drops. Always verify your refrigerator model number against the compatibility list before purchasing. Note that this unit is specifically designed for cold water lines only and must not be used with hot water systems.
