Next odor control purchase

I've read that ozone generators can be harmful, but was wondering how effective negative ion generators are? I know this one includes a carbon filter but was making the purchase for the negative ion generator part. Is this purchase worth the 50$? I already have a 440 Cfm phresh filter I just want something as a second line of defense

on your link it was just a page full of various items none were ion generators that I seen.

you have to search the item number for some reason.

So would it be better to get this or a second carbon filter?

The link is working fine in post 3. The title of it is "
[h=1]AIR PURIFIER CARBON IONIC IONIZER NEGATIVE IONS PRO UV STERILIZER BREEZE CLEAN"[/h]

Not an Ozone generator.
Doubt your going to get the effect you want from an Ionizer.

I ran an Ozone gen. outside of grow area, never in.
