AIR IONIZER, does it emit to much ozone for babies?

Is an Air Ionizer safe for babies?
I bought an air purifier with option for air ionizer, is it safe to use the ionizer with a baby in the room?
Will it have adverse effects on the baby or will it benefit him?
I only know that the purifier will help him because it will clean the air, I dont know about the ionizer.
Thanks
