Is My Sub-Zero 7007067 Air Cartridge Discontinued? (Meet the 7042798)

You went to order a replacement air cartridge for your Sub-Zero, dug out the old part number 7007067, and came up short. Maybe the number looks different on the new filter. Maybe a listing told you it's "no longer available." So here's the question on your mind: is the 7007067 discontinued, and if so, what do I buy instead?

Good news — your refrigerator isn't orphaned, and you don't need a new fridge. The short version: the part number changed, the filter didn't disappear. Let's clear it up so you can order with confidence.

The short answer: it's superseded, not discontinued

The Sub-Zero 7007067 air purification cartridge has been replaced by the current genuine part, the 7042798. Per Sub-Zero's own documentation, "Part number 7042798 is a direct replacement for previous part number 7007067." Same job, same fit — just an updated number.

This happens all the time with appliance parts. Manufacturers roll part numbers forward as packaging, labeling, or sourcing changes, even when the component itself stays the same. So if you're holding a filter (or an owner's manual) that says 7007067, the part you want today is the genuine Sub-Zero 7042798 air purification cartridge.

👉 Tip: You may also see the number 7007076 floating around on third-party listings. When in doubt, order by the current Sub-Zero number — 7042798 — and you'll get the right part.

7007067 vs. 7042798: what actually changed

Honestly? Not much, and that's the point. The 7042798 is the same air purification cartridge your Sub-Zero was designed to use — it just carries the current part number. Here's the side-by-side:

In other words: if a cartridge in your hand says 7007067, you don't need to match that number. You need its successor.

Will the 7042798 fit my refrigerator?

If your Sub-Zero has an air purification system, yes. Sub-Zero states the cartridge is compatible with all models that include air purification — and it's the only air filter in the unit. That covers a wide range of built-in and column refrigerators, including:

• Classic (BI / CL) built-in models
• Designer (IT, IC, DET, DEC) column models
• Tall models and Drawer models ID-30RP and ID-36RP
• Professional PRO4850 and PRO3650

The one exception: All-Freezer units do not have air purification, so there's no cartridge to replace there. Everything with a fresh-food compartment and the air system takes the 7042798.

Why it's worth getting the genuine OEM cartridge

You'll find plenty of cheaper "compatible with 7007067/7042798" filters online. Here's why we only sell the genuine Sub-Zero part — and why we think it matters for a refrigerator in this price class.

The air purification system in your Sub-Zero isn't a simple charcoal pad. It uses NASA-developed technology that scrubs the air of ethylene and odor roughly every 20 minutes. Ethylene is the gas your produce gives off as it ripens — pull it out of the air, and your fruits and vegetables stay fresh longer. The genuine cartridge is built and calibrated for that system. We want your filter doing the job Sub-Zero engineered it to do, not just filling the slot.

When should you replace the air cartridge?

Sub-Zero recommends replacing the air purification cartridge after about 365 days, or if the cartridge bulb burns out. Your refrigerator helps you keep track with an air-filter icon on the control panel (it looks like a sheet of paper with three wavy lines):

• No icon showing — the air purification system is turned off.
• Steady icon — the system is on and working normally.
• Flashing icon — time to replace the cartridge.

One important note: swapping in the new cartridge alone won't stop the flashing. You also have to reset the filter life on the appliance itself. The exact steps vary by series — we cover them in our guide to clearing a flashing Sub-Zero air purification icon.

👉 Good to know: An unopened air cartridge has no shelf life. As long as it's not plugged into a unit, there's no expiration or "use by" date — so buying a spare now to have on hand is a smart move, not a gamble.

How to buy the right one (and skip the guesswork)

Here's the simple path forward if you've been searching for 7007067:

1. Order the genuine Sub-Zero 7042798. It's the current, direct replacement — shop the 7042798 air purification cartridge here.
2. Due for a water filter too? Most Sub-Zero owners replace both filters on a similar yearly cadence. Our water + air filter combo pack pairs the 7042798 with the genuine 4204490 water filter and saves you a second order.
3. Keep a spare. Since the cartridge doesn't expire on the shelf, stocking one means you're never caught waiting with a flashing icon.

Frequently asked questions

Is the Sub-Zero 7007067 discontinued?

Not in the sense of being unavailable — it's been superseded. Sub-Zero lists the 7042798 as a direct replacement for the previous 7007067 part number. Order the 7042798 and you've got the correct current cartridge.

Is the 7042798 the same as the 7007067?

Functionally, yes. The 7042798 is the current genuine air purification cartridge that directly replaces the 7007067. Same fit, same twist-in installation, same role in your refrigerator's air purification system.

Will the 7042798 work in a fridge that originally came with the 7007067?

Yes. Because it's a direct replacement, any Sub-Zero that used the 7007067 takes the 7042798 — no modifications, no adapters.

Do I have to use the genuine Sub-Zero cartridge?

Nothing forces you to, but we strongly recommend it. The air purification system uses NASA-developed technology tuned for the genuine cartridge, and generic "compatible" filters aren't tested or validated by Sub-Zero. For a refrigerator at this level, genuine OEM is cheap insurance.

How often should I replace it?

About once a year, or when the air-filter icon flashes or the cartridge bulb burns out. Remember to reset the filter life on the appliance after installing the new one, or the reminder will keep flashing.

Can I buy the water filter and air cartridge together?

Yes — the combo pack bundles the genuine 4204490 water filter with the 7042798 air cartridge, which is handy since both are typically replaced on a yearly schedule.
