AC3000 - Air Purifier turns off

Your product is now equipped with an ECO mode. Eco mode is designed to reduce unnecessary electricity usage to maintain a healthy air quality. 

Here is how it works:

If the AQI is 10 or less, the motor will turn off for 30 minutes (the AQI must stay below 10) and then it will turn on to fan speed 1 for 5 mins. If the AQI is still 10 or below after this, then the motor will shut off again and the cycling of 30 minutes off, and 5 minutes on will repeat until the AQI goes above 10.

To exit auto mode, simply press the Fan Speed button to cycle through the remaining speed levels.

One thing to note is on the AC3000 you will not see the digital read out of the AQI as this is monitored internally within the units sensors. 

The reason the unit turns off, is because on the ECO mode, the Air Purifier does not run to clean the air consistently when the AQI is below 10, when using the ECO model. That reading indicates the air is very healthy. Once the AQI increases, the unit will turn on consistently in order to clean the air to get the reading below 10 again.
