Filter assembly and filtering system having the same

Abstract

Proposed are a filter assembly and a filtering system having the same. The filter assembly of the present invention is characterized in that it comprises a first pleated part formed from zigzag-type pleats continuously formed thereon; a second pleated part having zigzag-type pleats continuously formed thereon and being connected adjacently to said first pleated part, said second pleated part being formed with a height lower than that of said first pleated part so as to provide a seating place; a pair of end strips connected to the two ends of the first pleated part and the second pleated part along the length of the pleat; and a diffusion member which is seated in the seating place, and in that the flow of air that is filtered through the second pleated part passes through the diffusion member. According to the present invention, filtering is carried out throughout the entire region in which the flow of air moves in that said invention is equipped with a diffusion member which is seated in the seating place, and a function of aromatic substances, antibacterial agents and dehumidifying agents is added, and the replacement interval for the aromatic substances, etc. can be easily and effectively measured in that the invention is equipped with a diffusion substance measuring sensor, which is installed on one side of the filter channel in which said filter assembly is installed, and measures the flow of air that passes through the filter assembly.
