Carbon Scrubber or Ozone?

Im debating on what odor system to invest in and im interested in what system worked best for all of you. Also, id like to know if it would be a good idea to place these items in my grow room or outside of it.

i have never used a ozone but i bought a carbon scrubber from htg supply and it works good

carbon scrubber every time, if you instsll it with a powerful in line fan and change the activated granules every 4 or 5 grows there is o readson why you cannot get rid of all the unwanted odours from your grow room

i grow in my house in a tent and use carbon filters and a few ona blocks, one in the exhaust from the tent and one tied to the fan next to my window and there is no trace of odor

Carbon Scrubber is what I use. It clears the oder out instead of masking it.
