According to the present invention, an air purifier, in which an intake and an exhaust are carried out by a vertical movement of a piston (107), is formed as a cylindrical transparent main body (100) and a filter tank (200) are detachably combined. In addition, the cylindrical transparent main body (100) comprises: valves (103 (a), 109 (a)) open only toward the inside of a valve; valves (103 (b), 109 (b)) open only toward the outside of a valve; a cover (102) having an air intake hole (104) connected for flowing air through the valve (103 (b)); the piston (107) vertically moved in the height direction of the cylindrical transparent main body (100); a main body pipe (105) which transfers the air to the filter tank (200); and an air discharge hole (114). The filter tank (200) comprises: a filter tank pipe (202); a suction pipe (203); and a metal filter (204). |
