Key Features
Advanced Contaminant Reduction: Activated carbon filtration helps reduce impurities such as chlorine taste and odor for cleaner, fresher drinking water.
Certified Quality Construction: Manufactured to Sub-Zero’s strict performance standards for long-term reliability in premium refrigeration systems.

How It Works
The Sub-Zero 7023812 filter uses an activated carbon block core that captures impurities as water flows through the cartridge. Once installed in the refrigerator’s filtration housing, it reduces chlorine taste, odor, and fine particulates to improve overall water clarity and freshness. The filter operates under normal household water pressure, and replacing it every six months keeps the water dispensing and ice making systems functioning at peak performance.

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
