- Water whitening phenomenon
All water provided to refrigerators flows through the core filter which is an alkaline water filter. In this process, the pressure
in the water that has flowed out of the filter gets increased, and massive oxygen and nitrogen become saturated. When this
water flows out in the air, the pressure plummets and the oxygen and nitrogen get supersaturated so that they turn into
gas bubbles. The water could look misty due to these oxygen bubbles. It is not because dust or chemicals, just a few seconds
later, it will be clean again.
