Water clouding phenomenon
All water provided to the refrigerator flows
through the core filter which is an alkaline
water filter. In the filtering process, the
pressure of the water that has flowed out
of the filter is increased, and the water
becomes saturated with oxygen and
nitrogen. When this water flows out into
the air, the pressure plummets and the
oxygen and nitrogen get supersaturated,
which results in gas bubbles. The water
may temporarily look misty or cloudy due
to these oxygen bubbles. After a few
seconds, the water will look clear.
