The commercial 10-second ozone O_³ machine disperses ozone with a concentration of less than 0.01 ppm, meeting national standards. Using this machine to clean vegetables only requires rinsing for 10 seconds, effectively removing 99% of bacteria and 80% of pesticide residues. This helps save on cleaning agents, water, and time. It also eliminates residual odors and unpleasant smells from dishes and utensils.
