For some models, fruit and vegetable box is with automatic humidity control. Fruits and vegetables will remain fresh for a longer time if they are stored in this compartment with automatically humidity control.
The fruit and vegetable box cover is equipped with an ecological plant membrane with respiratory function. If the humidity increases due to respiration of fresh vegetables, the structure of the membrane opens and allows excess moisture to escape to the outside air. If the vegetable/fruit loses too much water, the membrane prevents water evaporation. So fruits and vegetables box humidity can be maintained at optimum humidity of 90%.
