As long as you dont mind it killing the terpene smells too.
Ionizers oxidize everything. Maybe in a room disconnected to keep odors from being noticed but not in the grow room.
Its also unhealthy for humans so care must be taken.
My buddy spent a grand back in the 90s. Now, as cheap as 350.00. The filtered units look like they take up alot of valuable space. Have not found pricing on other options.
You wont need to look very far to find the information relating to its negative side affects.

I know what they did for odor control in the navy. 80 men in the same quarters. Not much odor, turn them off, in less than 30 minutes, you knew who hasnt done laundry in a while and other things.
They are tiny, yet can clear a 20x20 room of smoke.
