INDOOR AIR PURIFIER USING PHOTOCATALYST AND UV RAY

摘要

PURPOSE: Provided is an indoor air purifier being capable of purifying indoor air with high efficiency at low cost by eliminating dust and fine particles using a filter at first step, adsorbing odor and hazardous material using an AC/ACF filter at second step and finally deodorizing and sterilizing the treated air using photocatalyst and UV ray at third step. CONSTITUTION: The purifier comprises an inhalator(10) with an air inlet(20) for taking indoor air, a pretreatment filter(30) for eliminating dust and fine particles in the air, an intermediate filter(40), an AC/ACF filter(50) for eliminating odor and hazardous gas in the air, a UV lamp(60) and photocatalyst(70) for sterilizing the filtrated air, and a fan(80) for exhausting the sterilized air.
