Air Filter question (Ionizer, HEPA Filter)?

I just bought that, and it says it has an Ionizer in this. I read about Ionizers and it releases bad Ozones into the area that can cause chest pains, Does HEPA filters prevent that from happening? or do I turn the Ionizer off? or just leave it on and turn it off when I am not in the room?
