To control ion amount and aim at voltage reduction and frequency lowering of a voltage generator by improving the removal rate of contaminants by utilizing a radio frequency generating electrode and an ion generating electrode and by controlling the voltage of the ion generating electrode.
An air cleaning system is provided with an air stream passage 2 on the top of a clean room 1 and, on the upstream of the air stream passage 2, a moderately efficient filter 3 is provided. A dust neutralizing and flocculating system is constituted of a radio frequency generating electrode 10, an ion generating electrode 11 and a voltage generator 12 and is located on the downstream of the moderately efficient filter 3. Particles in indoor contaminated air without containing outdoor air are removed immediately by the moderately efficient filter 3. While fine particles passing through the moderately efficient filter 3 strengthen an inter-particle attraction force by depolarization by the radio frequency generating electrode 10, promote flocculation between the fine particles circulating in the indoor space by being added with cations and anions by the ion generating electrode 11, and are removed by the moderately efficient filter 3 after increasing the particle size.
