<p>PURPOSE: To prevent the concentration of cations in a space to be air- conditioned from becoming excessive. CONSTITUTION: In an air cleaner 1 having an ionizer part 15 and a duct collection part 21, a cation trap means 14 and an anion generation means 29 are installed downstream from the dust collection part 21. Since excessive cations generated in the ionizer part 15 are trapped by the cation trap means 14, or by generating anions positively, cations are not supplied to a space to be air- conditioned so that the concentration of cations in a space to be air-conditioned is prevented from becoming excessive.</p> |
