PURPOSE: An apparatus for reducing carbon dioxide is provided to eliminate fine dust in addition to carbon dioxide by including a filtering part composed of a pre-filter, a first absorbing filter, a second absorbing filter, and a high-efficiency particulate air(HEPA) filter. CONSTITUTION: An apparatus for reducing carbon dioxide includes a main body(100), a carbon dioxide sensor(160), a pre-filter, a first absorbing filter, a second absorbing filter, and a HEPA filter. The main body includes a filtering part and a fan. The filtering part absorbs carbon dioxide from air. The fan sucks external air. The carbon dioxide sensor measures the concentration of carbon dioxide by being installed at an indoor part. A controlling part controls the operation of the fan. The pre-filter eliminates dust. The absorbing filters absorb carbon dioxide. The HEPA filter eliminates fine dust. The pre-filter, the absorbing filters, and the HEPA filter are stacked. |
