Abstract:
An air-purifying device whose installation place has an elongate shape, air to which is supplied through a duct or a tube, and which can jet uniform purified air to the surrounding space of the installation place. A hollow-cylindrical filter (3) is constructed by providing a circular air passage (2) penetrating through the center of a filter material (1) formed in a hollow-cylindrical shape. Air inlet members (6) each formed by providing an air supply hole (5), communicating with the air passage (2), in a peripheral wall of a follow-cylindrical body (4) having the bottom are fitted and tightly fixed by a sealing member on an upper and a lower portion of the hollow-cylindrical filter (3), and thus an air-purifying device is obtained.
