The Smart Standing Fan 2 features smart control with support for the Mi Home app, Google Assistant and Amazon Alexa. This allows you to control the fan with your voice for a hands-free smart experience. The Smart Standing Fan 2 features two layers of fan blades that rotate simultaneously. This gives you increased airflow for more powerful cooling and with its wider reach, the dual blades also provide a more gentle three-dimensional breeze. You can easily switch between natural breeze or direct blow with fan speeds ranging from anything between 1 and 100 for fine-tuning. This can all be done in the Mi Home app, to achieve your desired airflow. The Smart Standing Fan 2 uses a DC copper-wire motor, which has higher operating efficiency and longer service life than an aluminium-wire motor. It also provides constant speed for more stable ventilation and lowers power consumption. To top it all off its wing-shaped blades produce a maximum airflow of 20m³/min. The Fan is also very versatile, allowing for usage that is perfect for any room. Its innovative design allows you simply press a button to easily adjust the height of the stand. This allows you to place it on top of a table or on the floor for convenience. Its ultra-wide angle of 140° provides great ventilation and can increase airflow. This adjustable wide-angle ventilation with a maximum range of 14m is able to cool the room for the whole family. With its smooth-running brushless DC motor and dual fan blades, the fan has been optimized to deliver an exceptionally quiet and disturbance-free experience. Thanks to a minimal operating noise of as little as 30.2dB(A), the Fan 2 can be as quiet as spending some time in a library.
