I used to on my old system it worked well. With this new system I'm trying to limit the amount of equipment so I haven't bought another ozone unit this time around. Even if I were to want to get one, I don't know how I would add it. I don't have a sump, and I don't know if my tunzee 9002 is ozone safe. Plus it will make the house stink, running it in the garage was fine, but the house gets locked down pretty tight to keep warm for winter.
