Older units built before serial number 4116297 rely on a carbon block design rather than the microbiological filter found in newer models, and the Sub Zero 7023812 Refrigerator Water Filter is the part built specifically for them.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eCheck Your Serial Number First\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp dir=\"ltr\"\u003eThis filter is only correct for refrigerators with a serial number below 4116297. That number is on the sticker inside the fridge, usually near the door hinge. Ordering the right refrigerator water filter replacement starts with confirming that number, since installing the wrong cartridge simply won't fit or seal properly.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eMade for Harder Water\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp dir=\"ltr\"\u003eSome homes deal with water conditions that push past what a standard filter can handle.
