Why Buy the Sub-Zero 4204490 & 7007067 Combo Pack?

Buying the Sub-Zero 4204490 and 7007067 combo pack instead of ordering each cartridge separately saves time, simplifies the annual maintenance schedule, and ensures both filtration systems are refreshed simultaneously at the best value price. Here is what you get with the 4204490 and 7007067 combo pack:

• NSF 42 and 53 certified water filtration for verified reduction of lead, heavy metals, and chlorine taste and odor through the full 300 gallon service life
• Activated carbon block water filtration for consistent VOC and contaminant reduction from the first use through the full 300 gallon service life
• Activated carbon air purification targets food odors and ethylene gas at the source rather than masking them inside the refrigerator cabinet
• Reduces ethylene gas released by ripening fruits and vegetables that accelerates spoilage in nearby produce stored in your Sub-Zero refrigerator
• Dual filtration coverage addressing both dispensed water quality and refrigerator air quality in a single purchase
• Tool-free installation for both cartridges with no plumbing or specialist knowledge required for either component
• Shared 12 month service life simplifying annual maintenance to a single replacement event covering both systems
• Best value option for compatible earlier generation Sub-Zero refrigerators replacing both cartridges on the same annual cycle

4204490 & 7007067 Combo vs 4204490 & 7042798 Combo

This is the most important section if you are unsure which Sub-Zero combo pack to order.

How do I check which Sub-Zero 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, the Sub-Zero 4204490 and 7007067 combo pack is the correct replacement to order. If it shows 7042798, the 4204490 and 7042798 combo pack is the correct replacement for your unit instead.

What happens if I order the wrong Sub-Zero 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 inside the refrigerator cabinet. Always confirm the air cartridge part number on the existing cartridge before placing your order.

How Often Should You Buy a Replacement Sub-Zero 4204490 & 7007067 Combo?

Order a fresh Sub-Zero 4204490 and 7007067 combo pack every 12 months to keep both filtration systems running at full capacity simultaneously. The 4204490 water filter is also rated for 300 gallons so households with higher water consumption may need to order a replacement water filter at the 300 gallon water filter life mark even if the 12 month service life combo pack period has not been reached. Buying the combo pack at the annual mark rather than staggering individual replacements keeps both systems refreshed simultaneously and simplifies the maintenance schedule to a single order each year.

FAQs

Yes. Buying the Sub-Zero 4204490 and 7007067 combo pack in a single order rather than purchasing the 4204490 water filter and 7007067 air cartridge separately is the most convenient and cost-effective option for compatible earlier generation Sub-Zero refrigerators replacing both on the same 12 month service life cycle.

Where can I buy the Sub-Zero 4204490 and 7007067 combo pack?

You can order the Sub-Zero 4204490 and 7007067 combo pack directly from the shop link on this page. Confirm both part numbers against your existing filter and cartridge labels before completing your purchase to avoid ordering the wrong Sub-Zero combo pack for your model.

Is the Sub-Zero 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 built for different Sub-Zero refrigerator generations. The 7007067 fits earlier generation Sub-Zero models while the 7042798 fits newer generation models. Always confirm the air cartridge part number before ordering to ensure the correct Sub-Zero dual filtration combo replacement.

Can I order the Sub-Zero 4204490 and 7007067 as individual replacements instead of the combo pack?

Yes. Both the 4204490 water filter and 7007067 air cartridge are available to buy separately. The Sub-Zero 4204490 and 7007067 combo pack is the best value option for households replacing both on the same annual schedule, eliminating separate orders and ensuring both filtration systems are refreshed at the same time.

How do I confirm the Sub-Zero 4204490 and 7007067 combo pack will fit my refrigerator before I buy?

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, the Sub-Zero 4204490 and 7007067 combo pack is the confirmed replacement to order. If the air cartridge shows a different number, check the compatible Sub-Zero combo pack for that cartridge code before purchasing.

Why does my Sub-Zero refrigerator still have an odor after replacing the 7007067 air cartridge from this combo pack?

A new 7007067 air cartridge reduces airborne odor compounds inside the refrigerator cabinet 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 replacement.
