Principle Introduction：
Nano：

Nanometer (nm) is a unit. 1nm = 10^-9 m. This product uses many different kinds of nano-materials to make the glazed surface of porcelain and the ceramic body more firm and smooth to reach the effects of pore less, anti-stain, anti-bacteria and self-cleaning.

 
Far-Infrared：

Far-Infrared Radiation (wavelength of 5.6um ~1000um, 1um=10^-6 m) exists in the rays from the sun and all objects in nature, including human body, animals, plants and rocks. Generally speaking, human body can emit the far-infrared radiation with the wavelength of 5um~30um. The infrared rays with the wavelength of 6um~14um are considered as good electromagnetic waves. Different from the low frequency electromagnetic waves emitted from electronic appliances, the infrared rays with the wavelength of 6um~14um are very important for the growth of human and other live forms. Currently, this effect has won the recognition of different biological association. 

 
Negative Ions：

Negative ions usually exist in locations such as beaches, forests, waterfalls and streams. That is why people feel the air is fresher in these locations. Moreover, some minerals in nature (such as tourmaline and bamboo coal) also can emit negative ions.
The major functions of negative ions are: purifying air, killing bacteria, neutralizing electromagnetic waves, anti-static, ridding bad smells and keeping the level of freshness.
