In addition, the filter 310 filters foreign substances in the air, such as harmful substances and fine dust, to produce an air cleaning effect, and the filter 310 may use those known in the art, for example, High Efficiency Particulate Air (HEPA). ) filter, ULPA (Ultra Low Penetration Air) filter, or any one of nanofibers may be used.

A HEPA filter is a filter that collects and filters fine non-woven fabric. According to the DOE standard, it can be classified as a HEPA filter if it removes 99.97% of particles with a size of 0.3 μm or larger in the air passing through it.

The ULPA filter is a finer filter than the HEPA filter and is known to filter 99.999% of particles with a size of 0.10 μm or more in the air passing through it.

Nanofiber refers to a fiber made of microfibers with a thickness of nanometer scale, and the types include polymer nanofibers and carbon nanofibers. Since nanofibers have a very large surface area per unit volume like general nanomaterials, when used as a filter material, it is known that the filtration efficiency is high and the pressure drop generated during the filtering process is small due to the high porosity. For example, a spinning solution is prepared by adding an organic solvent to a polymer material such as polyester sulfone (PES), polyacrylonitrile (PAN), and polystyrene (PS), and the spinning solution is electrospinning to form a web. It is possible to form a nanofiber filter made of (web).

The HEPA filter is generally made of a material of glass fiber or asbestos fiber, and it is preferable to fold or bend a filter formed of cotton to form multiple layers to form a unit type with a large passing surface area.

In an embodiment of the present invention, the filter 310 uses an H13 grade HEPA filter, and is folded or bent to increase the air purification efficiency in the size accommodated in the filter frame 320 to prepare for the volume of the filter 310 . Thus, it is possible to increase the purification efficiency by maximizing the surface area through which air can pass.
