I just wanted to say that I own an Air-Zone water ozonator and am extremely happy with it. It is sturdy, good looking and well made. I have used it every day for about a year and a half now.
For cleaning the air, I use an Aranizer and I like that alot too. It was a debate whether to go with the Aranizer or Air-Zone for cleaning the air. I read through all the messages on Cure-Zone and there was so much positive feedback on the Aranizer, I went with that one.
