Abstract: The present invention relates to a breathing guide device easily attached to an inner side of an air filtration mask which filters out foreign substances such as fine dust, pathogens, viruses, and dust in the air, and to a breathing guide device and a mask system comprising the same, characterized in that an exhaled breath of a mask wearer is discharged to the outside by the breathing guide device through a flow path separately provided from a flow path for an inhaled breath such that discomfort or an unpleasant feeling caused by carbon dioxide or odor from an exhaled breath remaining inside the mask can be reduced, in that an exhaled breath discharge path is blocked by the breathing guide device so as to minimize a glass fogging phenomenon caused by moisture contained in the exhaled breath when a mask wearer wears glasses, and in that the breathing guide device dually filters out pathogens, viruses, or odor from an exhaled breath of a mask wearer who is infected or suspected of being infected with a contagious disease so as to minimize the spread of communicable diseases or anxiety felt by a third person. The present invention can separately provide a breathing guide device (additionally an exhaust filter, etc.) which can be mounted on a general-purpose mask including a general filter unit, or provide a mask system including a mask together with a breathing guide device and the like in the form of a set.

Abstract: The present invention relates to a decomposition accelerator composition for decomposing exhaust gas using plasma reaction. According to various embodiments of the present invention, the decomposition accelerator composition includes: an alkaline electrolyte solution and a hydrogen donor. The hydrogen donor may include at least any one selected from a group consisting of urea water, methanol, ethanol, propanol, and butanol. A method for treating the exhaust gas using the plasma reaction is characterized in that the mixture of an alkaline electrolyte solution and a hydrogen donor is sprayed and treated during the plasma reaction. The hydrogen donor is at least any one selected from the group consisting of urea water, methanol, ethanol, propanol, and butanol.
