Ozone Laundry System

$5,000-$30,000 cash incentive per system

Ozone laundry systems transform ordinary tap water into O3, a powerful oxidizing solution, which help effectively clean clothes without chemical detergents or hot water. Because the system processes laundry with mostly cold water, washing requires less time and energy consumption.
