The Xiaomi Smart Tower Fan gives you a gentle, variable, stable and quiet breeze. The core advantage comes from the variable frequency DC motor, which has the advantages of lower noise, and improved stability whilst also conserving energy. It adopts the vortex cross-flow air duct design, with stable and comfortable rotating air exhaust of the air duct. The super-long air duct forms a strong wind force with a maximum air output of up to 541 m³/h, which can quickly blow away the summer heat. The Smart Tower Fan also supports Google Assistant and Alexa, allowing you to turn on the tower fan and adjust the gear by simply sending a voice signal. With noise levels as low as 34.6 dB(A), it can operate smoothly and quietly, bringing a refreshing and sound sleep for the whole night. Its 150° ultra-wide-angle three-dimensional ventilation can cool down quickly and speed up the airflow. With Mi Home app, has adjustable angles of 30°, 60°, 90°, 120°, and 150° can be selected, allowing you to cool the room for the whole family. For additional protection, a bladeless wind outlet and fine grille can protect your children’s fingers and avoid possible dangers. With a power as low as 3.5 W, it has a power consumption of only 3.48 kWh for a cool summer, and only consumes 1.19 kWh for running for up to 6 days at the highest-grade air volume. Its compact size is easy to store and because of its shape and design, it does not need much space. The base part is only slightly larger than a sheet of A4 paper.
