<p>An ionizer (12) for electrification of particles in the air, a collector (13) for trapping charged particles, an ozone decomposition filter (14) for decomposition of ozone generated on the ionizer (12), and a fan (15) for feeding the air from an air inflow port (11d) to an air outflow port (11e) are provided successively in this order from upward in a casing (11) having the air inflow port (11d) and the air outflow port (11e). The ionizer (12) and the collector (13) are disposed to surround the fan (15) inside the air inflow port (11d).</p> |
