By arranging the filter assembly 20 and the anion generating assembly 11 in the internal cavity 101 of the housing 10 at the same time, the filter assembly 20 covers the air inlet 100 on the housing 10, so that when air enters the internal cavity 101, pollutants in the air can be filtered by the filter assembly 20, and the filtering function of the suction type anion generator is maintained. By locating the anion generating member 11 outside the filter assembly 20, the size of the anion generating member 11 is not limited by the size of the filter assembly 20 compared to the case where the anion generating member 11 is located inside the filter assembly 20, and thus, the anion generating member 11 having a larger size can be conveniently used to improve the anion ionization efficiency.
