Is it necessary to have a carbon filter and an ozone generator to take care of the smell of 6 or so plants? If not, then which one is better?

And with the carbon filter, can I place the can in the grow room and have the air sucked through, or do I have to blow the air into the can? Sorry for the stupid questions, I'm new, lol.
