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
