Radiation heat (radiant energy) is absorbed by the surface of the earth and differs depending on the surface condition and temperature of the object to be hit. In particular, as the far infrared ray has a long wavelength and is absorbed well when it reaches the object, it is strong, and the body of person warms by far infrared rays.

The development of the technology to make far infrared ray with the beneficial wavelength to the human body will give healing to modern people suffering from noise, odor, heavy metal, and dust by creating a natural eco-friendly space.
Heating action of far infrared rays helps to eliminate germs that cause various diseases, and it helps to expand blood circulation by expanding capillary blood vessels. It is effective for sweating and relieving pain. , Sleeping, deodorization, prevention of mold propagation, air purification, etc., and it is also used as housing and building materials.
