Before describing the filtration device of the present invention for reference to the charcoal, first of all, the charcoal is a non-polluting substance that is left by pyrolysis of natural wood without additives at a high temperature (600 ℃ or more) and 80-90% solid carbon It is alkaline as PH8-9, and its characteristic is that the cell wall of the tree is carbonized and porous. The inner surface area of charcoal 1g is 200 ~ 400㎡ (about 100 pyeong), and the large hole has good air circulation through all directions, so it is widely used for adsorption, water-lowering agent, deodorant, etc. It is used as a health ingredient by using hardening properties.

Charcoal has ① anion generation effect ② air purification effect ③ humidity control effect ④ electromagnetic wave absorption effect.

First of all, ① look at the effect of generating anions, charcoal has an effect to increase the negative ions and negative ions affect the parasympathetic nerve to relax the mind and body, it is known to have a calming effect to stabilize the mood and relax the body. When you go to charcoal or the beach, you feel comfortable. This is the effect of negative ions. Around us, there are many home appliances known as sources of cations such as televisions and computers, and in places where there are many cations, tension is increased and they are easily excited and tired. However, if you put the charcoal around, the anion is increased by the char and neutralizes the cation, so that the air in the bedroom is in a balanced state, making the environment to sleep well.

② Looking at the air purification effect, charcoal is a porous microorganism habitat, and actinomycetes, which are excellent in decomposing organic matter, live well, so they adsorb and decompose contaminated components or harmful impurities in the air to purify the air and remove odors.

③ look at the humidity (調 濕) effect, the charcoal absorbs when the moisture is high and releases the moisture when it is dry to naturally control the humidity of the living room. Recently, the outside air is well blocked and there is no material that can be dehumidified by the surface coating process such as wood, so that the warm air containing moisture becomes saturated in the cold place such as glass window, and condensation occurs. It is the cause of mold, which is eliminated neatly.

④ Looking at the absorption effect of electromagnetic waves, electromagnetic waves are the flow of electricity and magnetism generated when using electricity, and are classified into short-wavelength radiation, ultraviolet / infrared rays, and long-wavelength microwave / low-frequency according to the length of the wavelength. Among them, a problem is microwave or ultra low frequency electromagnetic waves generated from home appliances. Charcoal has excellent adsorption, conductivity, and electrical storage, so if it is placed near electronics, it absorbs electromagnetic waves.
