This refrigerator has a special lattice-type box cover that maintains moisture at an excellent level. Moisture from the food is evaporated and then condensed on its lattice, and hence maintains the correct balance of moisture in the box. With this fridge at home, electricity bills will never be bothering you again, since this LG Refrigerator with 4 Star Rating* consumes 32% less power than the conventional Frost Free Refrigerator.
