REGENERABLE PHOTOCATALYST FILTER

摘要

Disclosed is a renewable photocatalyst filter. The renewable photocatalyst filter comprises: a base part; a photocatalyst layer formed by coating a photocatalyst to the base part, wherein the photocatalyst generates a photoreaction by reacting with ultraviolet rays; and a heating part which heats the photocatalyst layer to decompose contaminants attached to the photocatalyst layer by heat.
