a low voltage circuit board (106) disposed in the top compartment, the low voltage circuit board operatively coupled to the high voltage circuit board.

13. The air ionizer of claim 12, further comprising:
a feedback circuit board (108) disposed in the top compartment and operatively coupled to the low voltage circuit board.

14. The air ionizer of any of claims 10 to 13, wherein the modular case further comprises:

a front wall (124);

a back wall (126);

a first sidewall (128) coupled to the front wall and the back wall;

a second sidewall (130) coupled to the front wall and the back wall; and

a divider (132) coupled to the front wall, the back wall, the first sidewall, and the second sidewall, the divider separating the top compartment from the front compartment,

wherein the front wall, the back, the first sidewall, the second sidewall, and the divider define the top compartment.

15. The air ionizer of claim 14, wherein the modular case further comprises:
a bottom panel (134) coupled to the back wall, the first sidewall, and the second sidewall, wherein the bottom panel, the back wall, the first sidewall, the second sidewall, and the divider define the front compartment.
