The principle of "ozone disinfection" for automobiles is very simple. Using special disinfectants, the "ozone generator" creates a sterilized ozone mist, which is then circulated in the car through the air conditioning circulation system to remove the odor in the car and clean the car. Disinfect and sterilize every corner of the interior. The construction process of "ozone disinfection" is also very simple. You can see that there are two methods of disinfection in stores:

• Built-in "ozone generator"

Turn on the air conditioning system to circulate, turn on the "ozone generator" and put it in the car, close all the windows, and after about 15 minutes of disinfection, turn off the "ozone generator", open the door for ventilation, until the smell of the disinfection ozone and the medicine is all disperse;

• External "ozone generator"

Turn on the cycle of the air conditioning system, close the window, and introduce the air pipe of the generator into the car through the gap of the window, turn on the "ozone generator", and after disinfection for about 15 minutes, turn off the "ozone generator" and turn it on. The door is ventilated until the odor of the disinfecting ozone and the chemical has been dissipated.

• What is the subjective difference between built-in and external?

I have tried both methods. The cloud-filled "wonderland" scene with the built-in "ozone generator" is unforgettable, but the smell of the medicine will remain for a long time. It basically takes more than 30 minutes of ventilation before the owner can barely get on the car.

Using an external "ozone generator" for disinfection, the construction does not look so spectacular, the smell of the medicine is released faster, and the effect is relatively better.
