The basic concept of an ozone pool system involves injecting oxygen into the water supply to help disinfect and purify the water. This process is said to kill bacteria 3,000 times faster than chlorine. The system includes a heater, water pump, filter, ozone system, and control box. However, there is debate over whether ozone is healthier than saltwater, as ozone pools still require the addition of chlorine tablets and have similar chlorine level tests as any other pool.
