About This Item

• Made for older units: The 7023812 SubZero filter fits Classic (BI) refrigerators with serial numbers before 4116297. Newer units take the 4204490 filter, so check your serial number first.
• Handles harsh water: Some city and rural water clogs fine filters within a few months. Sub-Zero recommends this carbon block design for those homes, and it keeps flowing for a full year.
• Clean taste in every glass: This 7023812 water filter reduces chlorine, bad taste, odor, and color. Your water and ice come out clear and fresh.
• Push-in replacement cartridge: Push the old filter in to release it, then pull it out. Next, press the new 7023812 replacement cartridge in until it clicks.
• Quick first flush: Run the dispenser for a few minutes after you install it. This step clears air and loose carbon from the water line.
• Current part number: The SubZero 7023812 is the updated version of filter 7023811. It also replaces the older 7009931 and 7005017 cartridges.
