Only Twin Cooling Plus™ creates a favorable environment for preserving fresh food in the fridge with 70% humidity, compared to 30% in a conventional TMF. So it keeps ingredients fresh for longer without drying out. The Twin Cooling Plus™ system cools the compartments separately to stop unexpected odors spreading from fridge to freezer. So frozen food retains more of its original flavor.An Anti-Bacterial Protector keeps the fridge clean and hygienic. Air is passed through an Activated Carbon filter, so it is constantly sterilized and deodorized, while an anti-bacterial mesh eliminates bacteria.
