The Sub-Zero refrigerator model features a filtration system that is designed by NASA. The system filters the air every twenty minutes to eliminate the gases omitted by food, their odors, and bacteria. It also helps keeping the food looking and tasting fresh for longer periods than in regular fridges.
According to the Sub Zero website, the model comes with front panels for the framed design in white and classic stainless steel for a sleek look. Watch the video for more info.
