Keep fruit fresh longer

Produce is sort of infamous for its short shelf-life, but Sub-Zero's new refrigerator aims to reduce food waste and keep your carrots crisp longer.

We all want to eat healthy. We go to the grocery store with the best of intentions, bee-line for the produce aisle, and load up on fresh fruit and veggies. We cram all of it into the fridge and head off to make dinner. A week later, we learn that maybe we bought a bit more than we should have when we open the crisper and find our lovely butter lettuce has turned brown and begun to stink. It happens a lot; a recent study from the University of Arizona says that the average American household winds up with more than $500 worth of spoiled leftovers every year.

No fridge can keep food from ever spoiling, but Sub-Zero's new line--the Built-In Refrigeration Series--comes close. It has a freshness preservation system that relies on two compressors to separately control temperature and humidity in the fridge and freezer. Independent controls prevent the compartments from simply circulating the same air over and over again, and therefore reduce drying and slow the decay of fresh foods. Sub-Zero has also added an air purification system that helps slow the rot process even further by purifying that air that does get reused. Even if the reuse of air is limited, odors and bacteria wind up floating around your fridge. The Sub-Zero system purifies internal air every 20 minutes. The new Sub-Zero line will be on sale this fall.
