The Sub Zero 4204490 Refrigerator Water Filter brings back the clean taste your dispenser and ice maker are meant to deliver. It fits Sub-Zero's built-in and PRO series units, and it takes chlorine, sediment, and odor out of the picture before they reach your glass.
Fresher Taste, Right Away
Chlorine and its lingering aftertaste get pulled out before the water hits your glass, so every pour tastes the way it should.
Clearer, Cleaner Ice
Sediment that usually clouds your ice cubes stays trapped in the filter instead of your freezer tray, so the ice looks as good as it tastes.
Steady, Reliable Flow
A tired filter slows everything down. A fresh sub zero water filter cartridge keeps your dispenser flowing at the pace it was designed for.
Gentle on Your Refrigerator
Less sediment moving through the internal lines means less strain on your fridge's water system, so it keeps running smoothly for longer.
Made to Fit, Made to Last
This is a sub zero refrigerator replacement water filter cartridge built specifically for the housing behind your top grille. It twists in with a quarter turn, no tools and no plumber needed, and starts filtering the moment it locks into place.

Built for Everyday Sub-Zero Use
Every household leans on their fridge a little differently. Families who fill water bottles daily or run the ice maker often will move through capacity faster than a lighter user, but the 300 gallon rating on this sub zero water filter cartridge comfortably covers most homes across a six month cycle.
It's engineered specifically for Sub-Zero's filtration housing, so there's no adapter and no forcing a filter that wasn't made for the job. It simply locks into place the way the system expects, and stays consistent from the first glass to the last.
