We spent 23 hours on research, videography, and editing, to review the top picks for this wiki. If you want to keep your pool crystal clear and sparkling clean, then simply adding chlorine may not be enough. Utilizing an ozone generator as part of your sanitation system will keep your water looking better than you ever thought possible, no matter how often you use it, while minimizing, or even eliminating, your need for bad smelling, and potentially harmful, liquid or powdered chlorine. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best pool ozone generator on Amazon.

6. A2Z SP-5G

The A2Z SP-5G is a great way to get away from all the side effects of chlorine. The unit is fan-cooled, so you don't have to worry about overheating, despite frequent use. It's best if you cover it, however, as it may not stand up to exposure to the elements.
  • easy installation instructions
  • wiring is well-protected
  • fan is fairly loud
