The air purifier is a completely automated control that lowers fan speed when nec-essary and reduces sound. The air purifier will automatically change the indictor LED color and increase the fan speed when it detects smoke and air pollution in your room to purify it faster. When the air quali-ty is in acceptable levels then the fan speed will go down automatically thus help saving energy usage.
