How It Works

The filter uses carbon/charcoal filtration to reduce chlorine taste and odor, with a twist-and-slide installation that stops water flow during replacement for a clean swap-out.

Installation Instructions

1. Locate the filter in your refrigerator (usually in the door or grille).
2. Push and twist (or slide) the filter to release and remove it—water flow stops automatically.
3. Insert the new 46-9890 filter and push/slide until locked in place.
4. Flush several cups of water to clear out air and carbon residue after installation.
