Do you have a rotten egg smell in your water? Does it smell up your house, make your clothes stink and gag when you take a shower? You can’t drink it or Cook with it? You have hydrogen sulfide problem. The AquaOx will eliminate the bad smell and taste from the water in your whole house.
The only reason you would need this add-on system is if you can smell the water out in the room while sitting on your couch or right when you walk through the front door. If you have to bend down to smell the rotten egg smell at the tap or smell it in a glass, the regular system will solve this problem.
