Fridges with mid-range cooling quality have functions to store your groceries better or keep them fresh for longer. Most mid-range fridges No Frost. In a No Frost freezer, there's no ice buildup on products, which preserves their taste and texture. A fresh zone doesn't come with all mid-range fridges, but it does happen. Meat and fish, or fruit and vegetables stay fresh 3 times as long in a crisper drawer.
