The purifying member T2 will be briefly described as follows.

jade ;

Jade contains minerals, calcium, and magnesium that are extremely necessary for the human body. Among them, magnesium accounts for more than 40%, and magnesium is a constituent of chlorophyll. At the same time, the cells that make up our cells are also made of magnesium, so the Qi wave coming out of the jade and the Qi wave of the human cells are the same wave. Therefore, the wave emitted from breathing jade penetrates evenly into our human body cells and acts as a resonance resonance. Only jade has a breakthrough in maintaining health through tissue revitalization, blood circulation, weak alkalinization of blood, and excretion of harmful wastes from the body. It is a unique effect that can

silicon ;

Silicon is also called silicon. Silicon oxide SiO2, a relatively simple compound of silicon, has been known since ancient times, and silica sand was also used as a raw material for glass making in ancient Egypt. It is not produced in a free state in nature, exists as oxides and silicates, and is a major component of the lithosphere.

In the present invention, for example, a zeolite mineral containing silicon dioxide (SiO2) as a main component is used. A mineral called zeolite is a highly porous mineral and has strong adsorption properties, so it adsorbs suspended substances well. For the zeolite, for example, a commercially available zeolite ball manufactured in a certain ball shape is used. However, it is not limited to the shape, and any other shape of zeolite may be used.

elvan stone ;

Quartz Porphyry (麥飯石) is a grayish-white andesite porphyry, so named because the shape of the rock resembles a grain of barley. The components of elvan are Ge (germanium), SiO2, Al2O3, Fe2O3, CaO, MgO, K2O, NaO, TiO2, P2O5, MnO, TiO2, P2O5, MnO, etc. It is rich in content and its use is expanding day by day.

In modern times, studies on strong adsorption of elvan stone, precipitation of minerals, water quality control, and dissolved oxygen in water have been actively conducted. It is used in materials, manufacturing of far-infrared emitters, electromagnetic wave blockers, building exterior materials, etc.

ocher ball ;

The loess, which covers about 10% of the surface, contains a large amount of calcium carbonate (CaCo3). Due to this calcium carbonate, loess has the viscous force that does not break easily and turns into clay when water is added. Red clay is composed of silica (SIO2), alumina (Al2O3), iron, magnesium (Mg), sodium (Na), and potassium. The loess composed of these composition ratios and various enzymes emits a large amount of far-infrared rays essential for the growth of animals and plants, so loess is called a living organism. Loess is a honeycomb structure with a wide surface, and numerous spaces form a double-layered structure. In this sponge-like hole, a large amount of far-infrared radiation is absorbed and stored, and when it receives heat, it is emitted and stimulates the molecular activity of other objects. In other words, loess absorbs solar energy for many years, and as a silicon mineral, it can be simply called 'solar energy storage'. The enzyme components of ocher include catalase, diphenol oxidase, saccharase, and protease. Each of these enzymes plays a role in detoxifying, decomposing, fertilizing, and purifying.

charcoal ;

Charcoal has an infinite number of negative ions generated from carbon. Where there are many negative ions, a lot of negative ions are generated around the waterfall as small water droplets adsorb the surrounding polluting particles. Therefore, the effect of negative ions is refreshing and fresh like the air in the forest, which naturally gives a feeling of comfort to the body. Anion is said to have effects such as blood purification, mental stability, autonomic nerve regulation, immune enhancement, lung function enhancement, and cell activation. Charcoal also has purifying, deodorizing and filtering effects. If charcoal is put into the sewage, it will absorb the chemicals and detergents in the sewage, so even if the river is polluted, if it is filled with charcoal on the bottom, it becomes a clear stream with fish swimming in it. Charcoal also has a far-infrared emitting effect. It also has the effect of adsorption and removal of harmful substances.
