- the ion balance in the vicinity of the ion element can be maintained.
- the collision time of molecules during generation of positive ions can be shortened, wear of the ion element can be reduced, and similarly, the generation time of negative ions can be shortened, so that the adhesion time of siloxane can be shortened.
- siloxane can be removed by causing molecules to collide with the element when positive ions are generated. As a result, the above-mentioned problems can be solved and the lifetime of the ion generator can be increased.
