AIR-PURIFYING MODULE

摘要

The present invention relates to an air-purifying module in which a heater heats a filter unit to purify air, wherein the filter unit includes an inorganic coating having a plurality of air pores, and a catalyst layer formed by impregnating a portion or the entirety of the inorganic coating with a catalyst mother liquid. According to one embodiment of the present invention, an air-purifying module, comprises: an air-permeable filter unit; and a heater. An inorganic coating having a plurality of air pores is formed on the surface of the filter unit, and the filter unit has a catalyst layer formed by impregnating a portion or the entirety of the inorganic coating with a catalyst mother liquid, wherein the filter unit enables air to initiate a catalytic reaction with the catalyst layer under a predetermined temperature condition such that the air can be purified. The heater heats the filter unit such that the filter unit is maintained at said predetermined temperature condition.
