<p>PROBLEM TO BE SOLVED: To provide a dust collector which is safe, whose structure is simple, in which atmospheric dust removal performance is enhanced and which does not clog for a long period of time.SOLUTION: An electric dust collection filter unit includes: ionization means 7 for ionizing air on an upstream side; and a filter part 8 on a downstream side. The filter part 8 comprises mixed numerous charged fibers and conductive fibers, both fibers are arranged so as to be horizontal with respect to a ventilation direction, and it also includes a configuration in which the conductive fibers are connected to the ground. By creating a long and strong electric field having depth in the ventilation direction and collecting atmospheric dust, the electric dust collection filter unit can be acquired which can acquire high dust collection performance, and which can always maintain high dust collection performance.</p> |
