Spanish Cedar (scientific name: Cedrela odorata) is a precious wood commonly used for making cigar boxes, furniture, cabinets and musical instruments. Although its name contains "cedar", it actually belongs to the Meliaceae family and has nothing to do with the true cedar (from the Pinaceae family).

The water circulation humidification system is a device that maintains or regulates the environmental humidity by circulating water. Its core principle is to increase the air humidity through the natural evaporation or active atomization of water, and to maintain uniform and stable humidity through the circulation system.

Using high-precision micro-computer control for micro-humidification and micro-dehumidification, it achieves uniform, accurate and stable humidity, and takes good care of the delicate cigars.
