Sub Zero 4204490 Water Filter & 7007067 Air Purification Cartridge Combo Pack

Sub-Zero refrigerators handle two separate filtration jobs, water quality at the dispenser and air quality inside the compartment. Most owners manage them on different schedules, ordering separately and keeping track of two different replacement timelines. This combo pack aligns both replacements in a single order. The 4204490 water filter handles drinking water and ice. The 7007067 air purification cartridge addresses interior air quality, food odors, bacteria, and mold. Both run on the same six month replacement cycle, which means ordering them together keeps the maintenance schedule consistent without tracking two separate timelines.

What Is Included in This Combo Pack

4204490 Water Filter: The water filtration component for Sub-Zero Classic BI and CL series, Designer IT, IC, DEC, and DET series, and Pro 648PRO, PRO3650, and PRO4850 refrigerators. NSF 42 certified, reducing chlorine taste and odor, sediment, and heavy metals through activated carbon block filtration.

7007067 Air Purification Cartridge: The air filtration component for Sub-Zero models with the standard air purification slot. Independent laboratory testing suggests up to 85% odor reduction in real use conditions. The cartridge addresses bacteria, mold, and food odors inside the refrigerator compartment and is one of the more frequently replaced air cartridges in the Sub-Zero lineup.

Why Choose the Sub-Zero 4204490 and 7007067 Combo Pack

FAQs

What is the difference between the 7007067 and the 7042798 air purification cartridge?

The 7007067 is the older air purification cartridge used in earlier Sub-Zero models. The 7042798 is the updated cartridge compatible with newer Sub-Zero models and replaces the 7007067 in those units. They are not universally interchangeable. Check the label on the current cartridge before ordering this combo pack to confirm the 7007067 fits the specific refrigerator. If the current cartridge is a 7042798, the alternative combo pack pairing the 4204490 with the 7042798 is the correct choice.

Do the water filter and air cartridge need to be replaced at the same time?

Not necessarily. The 4204490 water filter is rated for 12 months or 750 gallons. The 7007067 air cartridge is recommended every 6 months. In practice, many households replace the air cartridge twice for every one water filter replacement. Buying them together in a combo pack still reduces ordering cost and effort compared to purchasing each separately, even on different schedules.

Does this combo pack fit all Sub-Zero refrigerators?

No. The 4204490 water filter fits Sub-Zero Classic series models with serial numbers after 4134313, Designer series, and Pro series refrigerators. Not all Sub-Zero models have an internal water dispenser, and not all models use the 7007067 air cartridge slot. Confirm both the water filter code and the air cartridge code on the current components before ordering.

How does the 7007067 air cartridge reduce food spoilage?

The 7007067 addresses ethylene gas that fruits and vegetables naturally emit as they ripen. Ethylene buildup inside the refrigerator compartment accelerates the ripening and spoilage of nearby produce. The cartridge scrubs interior air every 20 minutes, reducing ethylene concentration and extending the shelf life of produce stored in the refrigerator. Independent testing suggests up to 85% odor reduction in real use conditions.

Is this combo pack lower in cost than buying both components separately?

Yes. The combo pack pricing is lower than ordering the 4204490 and 7007067 separately. For households that replace both components on a regular schedule, ordering them together in a combo pack reduces both cost and the number of separate orders placed over the course of a year.
