It was difficult to adsorb charged dust and bacteria. Therefore, in the conventional air cleaner, only dust can be collected by the filter, and it is impossible to remove dust and bacteria of 1 μ or less. In addition, the conventional air purifier cannot be expected to have a deodorizing effect at all, and if it is desired to have a deodorizing effect, it can be considered to use activated carbon, but since the adsorption capacity is limited, it can be used in large rooms and people. It was difficult to apply it to an air purifier that requires long-lasting effect in a room with heavy access.
