The KitchenAid KUIC18NNZS with Clear Ice Technology provides the most preferred ice - a uniform 3/4" x 3/4" x 1/2" size and shape that is ideal for daily use or a variety of entertaining needs. The integrated filter helps to remove contaminants to help improve taste and clarity. For best results, the filter must be changed every six months. With Max Ice, ice is produced 56% faster, compared to normal mode, when ice is needed quickly. This unit holds 35 pounds of ice which ensures a generous supply of clear, fresh ice is conveniently at your fingertips. The Drop-Down Door allows a more custom installation with a design that removes the need to account for a hinge.
