## Description

Product description Sub-Zero Refrigeration From the moment a fig is picked, a clock begins to tick. For its flavor is never better, brighter, or sweeter than when it is perfectly ripe. Prolonging that freshness—that fleeting peak taste and texture—is the single-minded mission of Sub-Zero. Properly maintaining the air purification system in your Sub-Zero refrigerator ensures that it will scrub the air of mold, viruses and bacteria — contaminants too small for conventional filters — and lessen the ethylene gas that hastens food spoilage. Based on NASA Technology, the Sub-Zero refrigerator air purification cartridge scrub the air every 20 minutes to ensure freshness! The old part # was 7007067 and the new part number is 7042798. They are the same unit and will fit the same refrigerators. Sub-Zero Air Filteration Authentic Sub Zero Factory Certified Microbiological Purification System Fresher, more flavorful food! There’s more to preservation than keeping food cold. Sub-Zero extends freshness with pioneering refrigeration technology that precisely controls temperature, optimizes humidity, and scrubs the air of impurities. Important: Sometimes during the shipment process, the carbon from the inside the unit can deposit on the exterior of the unit. This is normal, and should not effect the performance of the unit. Please clean the unit with a paper towel before installation.

Review: OEM part, fits perfectly. - I usually get altenative solution for filters, etc. I used get whatever filter that worked for my previous Whirlpool refrigerator since it was simple mesh looking unit. But after checking out sub zero Air filter, I decided to get genuine. It looks like it has contact point that can communicate with refrigerator unlike others. Obviously it snaped right in the slot and see no issue.

### ⭐⭐⭐⭐⭐ Easy to Use and Replace
*by K***N on January 28, 2026*

Our home came with a Subzero refrigerator and the branded filter works perfectly. Installation is a snap, wipe off the bottom of the filter then simply raise the cover at the top of the refrigerator and unscrew the old filter, though be sure to have paper towels ready to sop up any water that drips. Screw the new filter in place and pour a few glasses of water to clear any filter debris which may be in the water line. Although the Subzero refrigerator has an indicator symbol that appears when the filter needs to be changed, it is a good idea to put a sticker on the end of the filter with the date it was changed and also add it to your phone's reminder calendar.
