Sub-Zero 7007067 Air Purification Cartridge Replacement

If the refrigerator smells stale, produce is spoiling ahead of schedule, or the Pure Air indicator is lit, the Sub-Zero 7007067 air purification cartridge is due for replacement. The 7007067 is the air filtration component for earlier Sub-Zero models equipped with the built-in air purification system. It actively scrubs interior air every 20 minutes using NASA-developed technology, reducing food odors, bacteria, mold, and ethylene gas inside the compartment.

Find the Right Sub-Zero Air Purification Cartridge

Two air purification cartridge codes exist across the Sub-Zero lineup. Confirm which one applies to the specific refrigerator before ordering.

The 7007067 and 7042798 are not interchangeable. Check the label on the current cartridge inside the refrigerator before ordering to confirm the correct part number.

Compatible Sub-Zero Refrigerator Models

The Sub-Zero 7007067 air purification cartridge fits all Sub-Zero refrigerators equipped with the standard air purification housing, including:

Sub-Zero PRO 48, PRO3650, PRO4850, 648PRO, 648PROG, BI-30U, BI-30UG, BI-36F, BI-36R, BI-36RG, BI-36S, BI-36U, BI-36UFD, BI-36UG, BI-42S, BI-42SD, BI-42SID, BI-42UFD, BI-48S, BI-48SD, BI-48SID, IC-18FI, IC-24CI, IC-24FI, IC-24R, IC-30FI, IC-30R, IC-36R, ID-24F, ID-24R, ID-27R, ID-30F, ID-36C, IT-30CI, IT-30FI, IT-30R, IT-36CI, IT-36R, IW-30CI

Not all Sub-Zero models have an air purification system. If no black cartridge housing is present inside the fresh food compartment, the specific model does not support the 7007067. Designer Drawer models ID-30R and ID-36R do not have air purification systems.

Why Buy the Sub-Zero 7007067 Air Purification Cartridge

• Eliminates food odors from onions, garlic, fish, aged cheese, and other strong-smelling items that transfer between stored foods
• Reduces ethylene gas that causes fruits and vegetables to ripen and spoil faster -- extending the shelf life of produce stored in the crisper
• Up to 85% odor reduction in real use conditions based on independent testing
• Tool-free snap-in installation completed in under a minute with no tools required
• 6 month replacement cycle keeps active purification performance consistent through the full service life

Sub-Zero 7007067 vs 7042798 Air Purification Cartridge

Are the 7007067 and 7042798 the same cartridge?

No. Both use the same NASA-developed activated carbon filtration technology, but they have different housing formats designed for different Sub-Zero model generations. Sub-Zero updated the part number from 7007067 to 7042798 for newer refrigerator models. They cannot be swapped between housings.

How to check which cartridge the refrigerator uses? 

Open the refrigerator and locate the black cartridge housing along the upper rear wall of the fresh food compartment. Remove the current cartridge and check the part number printed on the label. If it shows 7007067, this listing is the correct replacement. If it shows 7042798, order the 7042798 instead.

What happens if the wrong cartridge is ordered?

An incorrectly ordered cartridge will not seat properly in the housing. In some cases it may appear to fit but leave gaps at the connection point, allowing unfiltered air to bypass the cartridge entirely. Always order by part number, not by appearance.

How Often Should the Sub-Zero 7007067 Be Replaced

Replace the Sub-Zero 7007067 air purification cartridge replacement every 6 months regardless of usage volume. Unlike a water filter, the replacement cycle is time-based rather than gallon-based. The carbon media saturates based on odor concentration inside the compartment. Households that store strong-smelling items regularly may find the cartridge reaches saturation closer to the 4 to 5 month mark and should replace sooner.

How to Install the Sub-Zero 7007067 Air Purification Cartridge

1. Open the refrigerator and locate the air purification housing along the upper rear wall of the fresh food compartment
2. Grasp the bottom of the housing cover and rotate upward to open
3. Pull the old 7007067 cartridge straight out and discard
4. Wipe any carbon dust from the exterior of the new cartridge with a paper towel before installing
5. Insert the new cartridge firmly into the housing until it seats correctly
6. Press and hold the Pure Air button on the refrigerator control panel for 5 seconds to reset the indicator light
