A PURIFICATION FILETER USING PHOTOCATALYST

摘要

PURPOSE: A purification filter is provided to improve sterilizing efficiency by using an optical catalyst tube and purification filter. CONSTITUTION: A purification filter comprises: a UV ray lamp (100); multiple first optical catalyst coating plates formed with multiple conduction holes on the surface, and equipped along a longitudinal direction surrounding the outer periphery of the UV ray lamp; an optical catalyst tube comprising a second optical catalyst coating plate equipped along a longitudinal direction of the UV lamp crossing the first optical catalyst coating plate vertically; and housing (190) accommodating the UV ray lamp and optical catalyst tube.
