Keeping your Sub-Zero refrigerator performing at its best means staying on top of both water and air filtration. The 4204490 water filter and 7007067 air cartridge combo pack covers both in a single purchase, making annual maintenance simpler and more straightforward for compatible Sub-Zero refrigerator models.
The 4204490 is NSF 42 and 53 certified to reduce chlorine taste and odor, lead, and other common contaminants, while the 7007067 air cartridge works continuously inside the refrigerator compartment to reduce food odors and ethylene gas that accelerates produce spoilage. Always verify both part numbers against your refrigerator model before ordering to confirm the combo pack is the correct fit for your unit.

How do I check which combo pack my refrigerator needs?
Check the part numbers printed on both the existing water filter and air cartridge currently installed in your refrigerator. If the air cartridge shows 7007067, this is the correct combo pack. If it shows 7042798, the 4204490 and 7042798 combo pack is the correct replacement for your unit.
What happens if I order the wrong combo pack?
The water filter component is the same 4204490 in both combo packs, so a mismatch will only affect the air cartridge. An incorrectly ordered air cartridge will not seat properly in the housing and will not deliver effective air purification. Always confirm the air cartridge part number on the existing cartridge before ordering.
How Often Should You Replace the Sub-Zero 4204490 & 7007067 Combo?
Replace both cartridges in the combo pack every 12 months. The 4204490 water filter is also rated for 300 gallons, so households with higher water consumption may need to replace the water filter at the 300 gallon mark even if the 12 month period has not been reached. Replacing both cartridges together at the annual mark rather than staggering replacements keeps both filtration systems running at full capacity simultaneously and simplifies the maintenance schedule to a single replacement event each year.
How to Install the Sub-Zero 4204490 Water Filter
- Locate the water filter housing inside the Sub-Zero refrigerator fresh food compartment
- Twist the old filter counterclockwise until it releases from the housing

- Align the new filter with the housing inlet and insert it firmly
- Twist clockwise until it locks securely into position

FAQs
Is the 4204490 and 7007067 combo the same as the 4204490 and 7042798 combo?
No. Both combo packs include the same 4204490 water filter but pair it with different air cartridges. The 7007067 is designed for earlier generation Sub-Zero models while the 7042798 fits newer generation models. Confirming the air cartridge part number on your existing cartridge before ordering avoids receiving the wrong combo pack.
Can I buy the 4204490 and 7007067 separately instead of as a combo pack?
Yes. Both the 4204490 water filter and 7007067 air cartridge are available as individual replacements. The combo pack is the more convenient option for households that replace both on the same annual schedule, eliminating separate orders and ensuring both filtration systems are refreshed at the same time.
Does replacing both cartridges at the same time actually make a difference?
Yes. Running a fresh water filter alongside an exhausted air cartridge means one system is working at full capacity while the other is not. Replacing both together ensures consistent performance across both filtration systems simultaneously rather than allowing one to drag behind the other.
Why does my Sub-Zero refrigerator still have an odor after replacing the 7007067 air cartridge?
A new cartridge reduces airborne odor compounds but does not remove odors embedded in refrigerator surfaces or food containers. Wipe down interior surfaces, check for spoiled food, and allow 24 to 48 hours for the new cartridge to reach full adsorption capacity before concluding there is an issue with the cartridge.
How do I confirm this is the right combo pack for my Sub-Zero refrigerator?
Check the part numbers on both the existing water filter and air cartridge currently installed in your unit. If the water filter shows 4204490 and the air cartridge shows 7007067, this combo pack is the confirmed replacement. If the air cartridge shows a different number, check the compatible combo pack for that cartridge code before ordering.
Where is the air cartridge housing located in my Sub-Zero refrigerator?
The air cartridge housing is typically located along the upper rear wall inside the fresh food compartment. The exact position varies slightly by model, so consulting the user guide for your specific Sub-Zero refrigerator confirms the precise location if it is not immediately visible.
