You can choose the “Clean Air and Humidity” mode to clean and humidify the air simultaneously.

The humidifier mode can especially help in relieving congestion, dry and swollen nasal passages,  etc. For improved air quality in colder weather conditions, the humidifier mode works the best.

Cleaning Modes

You can choose from 3 cleaning modes like “Clean Air”, “Clean Air & Humidity” and “Quick Clean” mode.

As the name suggests, clean air mode is only air purification.  Whereas, clean air & humidity mode is purification plus humidifier. The Quick Clean mode provides aggressive air filtration.
