Without additional energy, you can enjoy the water in its ideal temperature for healthy drinking.

The phenomena is as archaic as the Pharaohs, the water seeps slowly true the unglazed porous clay body and evaporates on the surface, which conducts the heat out, cooling the inside.
For efficiency reasons, the body is spherical, containing 3 liters, the level can be seen true the glass indicator.

Evaporation causes limescale deposits, which aren’t percepted over the white clay body. The cover guides the water flow, enables refilling and keeps the dirt away.
