Generally, a house, an apartment or an office is designed and constructed with a closed structure in order to improve the cooling, heating and noise shielding function, so that the indoor air or the outside air can not circulate indoors and outwards, There is a problem of accumulation in the room.

These ultrafine dusts are transported to the lungs by breathing and air is sent from the lungs to the outside world. In this process, ultrafine dust accumulates in the room and body, ultimately harming the health of the human body.

In the room, harmful exhaust gas (hereinafter referred to as " ultrafine dust ") such as smoke generated when food is cooked, odor of bathroom, cigarette smoke and carbon monoxide, carbon dioxide, There is a problem that various diseases occur due to ultrafine dust generated in the room.

In recent years, ultrafine dust caused by various emission sources has become serious enough to be a social problem.

In the past, in order to prevent inflow of foreign dust or polluted air, it was necessary to ventilate, but the window could not be opened at all. Conventionally, a conventional air purifier has been developed to purify indoor air. However, in general, a method of sucking indoor air containing ultrafine dust generated from the outside and purifying the indoor air, The cleaning ability is deteriorated, and there is a disadvantage that a large amount of dead space is generated in which the indoor space is not cleaned by the air purifier.

In addition, it has been pointed out that there is a fatal problem such as the inability to purify indoor air pollution caused by yellow dust or the like.

This is because air purification is rarely performed during ventilation, and when the room is sealed, particulate carbon monoxide, nitrogen oxides, and carbon dioxide are limited in terms of dust collection and adsorption.

However, in this method, only dust, some odorous substances, A person in the room sucks in dust, some odor substances, and organic compounds through respiration at the same time.

Indoor air quality is generally higher than that of outside air due to poor air ventilation and contamination from cooking, smoking, painting materials of furniture and clothes, concentration of carbon monoxide, volatile organic compounds, carbon dioxide, nitrogen oxides, Is high.

General household air purifiers installed to improve the indoor air environment are intended to improve dust collection and adsorption, or to remove dust and odors by using catalysts and ozone, but the pollution level of indoor air is high As a result, the equipment is complicated and the quality of purified air is low.

In addition, although the adsorption method initially exhibits excellent performance, when the adsorption amount of the adsorbent is exceeded, the air quality is rather deteriorated, and if the periodic replacement is not possible, there is a problem that the microorganisms propagate on the filter layer to further deteriorate the air quality.
