Buy the Sub-Zero 7042798 Air Purification Cartridge Online
Tired of opening your Sub-Zero and catching whatever smell got trapped in there overnight? The 7042798 is Sub-Zero's electrically powered air purification cartridge, actively scrubbing interior air rather than just passively soaking up odors, and it snaps into place in under a minute with no tools needed.
That Fridge Smell Isn't Just Bad Luck
Once your Sub-Zero's air cartridge is past its service window, odors, bacteria, and ethylene gas start building back up inside the compartment. That means leftovers pick up smells from whatever's sitting near them, produce spoils faster than it should, and no amount of wiping down shelves fixes the actual cause. A fresh 7042798 solves it at the source.

Why Grab Your Replacement Here
Active air purification that scrubs interior air every 20 minutes, not a passive carbon pad Reduces airborne bacteria, mold, and ethylene gas that speeds up spoilage Cuts down on flavor transfer between strong-smelling foods stored in the same compartment Snap-in installation finished in under a minute, no tools required Multi-pack options available if you'd rather stock up and skip reordering Priced below what you'd typically pay through Sub-Zero directly, with free USA shipping and a 30 day return window
How Often Should You Replace This Cartridge?
Plan on a fresh 7042798 every six months, twice a year, for consistent performance. Since this is an active system rather than a passive filter, waiting past that window means your fridge loses more than just odor control, it starts letting airborne bacteria and ethylene gas build back up too. If food seems to spoil faster than it should, or you're noticing flavor transfer between items in the fridge, that's usually a sign the cartridge is overdue.
Is This the Right Air Filter for My Sub-Zero?
This cartridge is built for Sub-Zero refrigerators, freezers, and wine storage units equipped with an air purification slot, not every Sub-Zero model has one. If your unit has a black cartridge housing inside the compartment and a Pure Air indicator on the control panel, this is your replacement. If you're not sure which cartridge code your current one uses, check the label directly before ordering.

FAQs
Why should I buy the 7042798 here instead of through Sub-Zero directly?
You'll pay less for the same factory certified purification performance, plus you get free USA shipping and a 30 day return policy if it isn't the right fit.
Should I buy a single cartridge or a multi-pack?
If you replace every six months as recommended, a 2 or 3 pack covers you for a year or more without needing to reorder, and it's a simple way to save a step later.
How fast will my order ship?
Orders are processed quickly with free shipping across the USA, so you're not waiting weeks for a replacement cartridge.
What if I order this and it turns out to be the wrong cartridge for my Sub-Zero?
You're covered by a 30 day free return and refund policy. Confirm your unit has an air purification slot and check the cartridge code before ordering to avoid a mismatch.
Does every Sub-Zero refrigerator use this cartridge?
No. Only Sub-Zero refrigerators, freezers, and wine storage units with a dedicated air purification slot and Pure Air indicator use this cartridge. Check inside your unit for the cartridge housing before ordering.
