A material for sterilization and deodorization according to the present invention comprises: a porous molded body formed by compressing and heat-treating aluminosilicate-based inorganic particles; and sodium chlorite present by being adsorbed on the surface and pores of the porous molded body. Thus, the material is excellent in durability, has excellent sterilization performance and deodorization performance by discharging chlorine dioxide gas according to atmospheric exposure, and exhibits an effect of continuously maintaining the initial performance for a long time. In addition, the degree to which sodium chlorite contacts and reacts with the atmosphere is controlled so that environmental and stability problems caused by chlorine dioxide emitted by the reaction can be overcome. Since the duration of natural decomposition can be controlled, there is an effect of making it possible to use the material in an environmentally friendly manner in the natural environment and ecosystem.

Provided is an indoor air cleaning device for a vehicle using a nonthermal plasma and an operation method thereof, and more particularly, to an indoor air cleaning device for a vehicle using a nonthermal plasma, in which ozone is generated by a nonthermal plasma through corona discharge and an air purifying filter is sterilized through strong oxidization action of ozone, achieving more hygienic and continuous management, static electricity of an electrostatic filter is recharged with the controlled magnitude of applied voltage to maintain the best purification performance of the filter, and negative ions beneficial for human body are generated, creating pleasant indoor air conditions.

A built-in apparatus and method for treating air including a housing with an air inlet and an air outlet. An air mover positioned near the air outlet is configured to draw the air through the air inlet. The housing encloses an air treatment zone, such as including an oxidizing zone, and an ozone removal zone positioned downstream of the air treatment zone and oxidizing zone. The air treatment zone includes UV light and/or ozone that partially oxidizes the chemical contaminants in the air treatment zone. A catalyst in the oxidizing zone oxidizes elements within the air treatment zone. The ozone removal zone includes a second, different catalyst material. A UV bulb that may or may not generate ozone is positioned within or downstream of the first and/or second catalyst materials to assist catalyst oxidation and/or self-clean the apparatus.

Provided are an indoor unit of an air conditioner and a method for controlling the same, the air conditioner includes a humidification module to generate steam, mix the generated steam with filtered air to generate humidified air, and spray the humidified air at a discharge outlet through an independent flow path to provide the humidified air to an indoor space, in a smart care mode, performs a humidification operation during a heating operation to discharge the humidified air together with heat-exchanged air, automatically switches a mode between a high speed mode and a comfortable mode to prevent frequent on and off, thereby saving energy, and automatically switches an operation mode thereof according to a temperature and humidity to control discharged air and the humidified air, thereby effectively supplying air with adjusted temperature and humidity.
