<div class="content-service-view">
<p class="info-desc">
In refrigerators with water purifying functions, the UF type filter does not remove useful minerals (calcium, magnesium, etc.) from the water.<br/>
However, because of such mineral components, white mineral deposits are formed when water evaporates or freezes.<br/>
This is the same phenomenon that occurs when heating or freezing spring water (such as Samdasoo spring water).<br/>
Mineral components remain just as particles in ice or cold water and then melt naturally when the ice melts and the water gets warmer.<br/>
Minerals such as calcium and magnesium are always present in tap water, spring water, and underground water, and are harmless to the human body.
</p>

<h3 class="sub-tit">Are there any white deposits around the outlet?</h3>
<p>
When fine pieces of ice or purified water on the outlet evaporate, the mineral components dry white and adhere to the appliance.<br/>
There may be white deposits around the outlet, which are harmless to the human body.<br/>
If there are white mineral deposits, wipe them away with a clean, lint-free cloth.<br/>
Except in cases of disassembly and reassembly for simply cleaning away mineral deposits, it is necessary to have it checked by a service technician through a visit.
