A method for manufacturing antibacterial reinforced filter containing phytoncide component {A filter include a phytoncide composition and its manufacturing method}

The present invention relates to a method for producing a filter containing a phytoncide component capable of maintaining the antibacterial action of cypress (hereinafter referred to as "phytoncide"). More specifically, it is a method for manufacturing a filter used in an air cleaner, an air conditioner, an air conditioner, a dehumidifier, an automotive air conditioner, an air filter, an electric vacuum cleaner, a clean room of a semiconductor laboratory or a biotechnology laboratory, etc. The present invention relates to a method for producing an antibacterial filter comprising a method of applying the leaf powder of ethanol, and applying the phytoncide extract extracted from a cypress tree to an optimal formulation in a secondary formulation.

In general, an air purifier is a device that purifies polluted air and converts it into fresh air, and has various uses such as home, vehicle, and industrial use. Due to the increasing environmental pollution, various respiratory and skin diseases, and yellow dust threats, interest in environmental clean-up in the home is increasing, and the air purifier market is expanding due to the special effects of well-being.

The outdoor air has a natural purifying function, but the need is increased because the air in a closed room has no self-cleaning ability. Therefore, in selecting a filter for purifying outdoor air, as interest in health increases in recent years, the application of far-infrared radiation, anion radiation, and antimicrobial materials for health promotion is expanding.

The cypress (Chamaecyparis obtusa), also called cypress, is an evergreen tree of the genus Cypressaceae, which is native to Japan, but is widely cultivated as a planting species in southern Korea through its development. It is used as a deodorant and an antibacterial agent.

Phytoncide, produced from cypress, is a plant's self-defense substance, which is spouted or secreted by plants to resist pathogens, pests, fungi, etc., and contains sterilization and insecticides. Phytoncide constituents are organic compounds composed of phenolic compounds including terpenes, alkaloids, glycosides, etc., and are known to have antimicrobial, sedative, deodorant and stress relief effects. Such phytoncide is a natural substance, not a chemical synthetic substance, is absorbed into the human body without difficulty, and selectively sterilizes harmful bacteria.

In addition, phytoncide is known to have a number of functions, such as antibacterial, deodorant, sedative and stress relief. In addition, phytoncide cleanses and moisturizes the skin with excellent sterilization, antibacterial and cleansing action, and strengthens the body's immune function.

Inhalation of phytoncide has been reported to significantly reduce the concentration of the cortisol, a stress hormone, and it is known that phytoncide does not cause bad odors even if the carcasses decay in the forest. It also helps to calm the central nervous system and make you feel comfortable, extend your sleeping time and help you get a good night's sleep.

In addition, it has been found to be effective in hyperlipidemia and thrombotic heart failure by improving the blood circulation system, and is also known as a strong antibacterial action that does not cause resistance in the human body. Phytoncide, a natural substance, is known to be most effective in preventing allergens without side effects because it has the effect of avoiding dust mites up to 90%.

Drinking phytoncide not only has antimicrobial and air purifying ability but also relieves stress, strengthens intestinal and cardiopulmonary function, and enables sterilization of the room. Recently, various studies on the use of phytoncide have been made, but as a filter Scientific experiments are inadequate.
