In the case of a conventional filter air cleaner, a high efficiency particulate air (HEPA) filter is generally used to increase the cleansing ability, and the power loss is increased due to an increase in pressure loss due to the high efficiency HEPA filter. do.

Therefore, there is a limit in making a large-capacity air cleaner, and there is a difficulty in cleaning the filter contaminated by dust. In addition, the maintenance cost according to the maintenance of the use is increased by the frequent replacement cycle of the filter, the price of the air cleaner and its maintenance cost is increased by the use of a high-efficiency filter used to increase the purification efficiency.
