Features and benefits

Why I love MIJIA Smart DC Frequency Conversion Tower Fan 2nd

• Advanced Airflow Technology for Unparalleled Comfort: The MIJIA Smart DC Frequency Conversion Tower Fan 2nd redefines personal cooling with its innovative internal design. It incorporates 10 sections of cross-flow wind wheels, each equipped with 35 drum blades, culminating in a total of 350 blades that meticulously cut the airflow. This sophisticated mechanism ensures a remarkably soft, gentle, and delicate breeze, effectively eliminating the harsh, stiff sensation often associated with traditional direct-blowing fans and preventing discomfort during prolonged use. Furthermore, its 0.6m super long air outlet, combined with a 150° ultra-wide-angle oscillation, delivers a comprehensive ring air supply capable of reaching distances up to 10 meters, guaranteeing consistent and uniform cooling across expansive rooms exceeding 25㎡.
• Intelligent Wind Modes and Deep Customization: This fan offers a versatile selection of cooling experiences, including Natural Wind, Sleep Wind, and Direct Blowing (Prevailing Wind) modes. The Natural Wind mode is particularly noteworthy, as it meticulously simulates the irregular and fluctuating wind speed changes found in outdoor environments, such as lakeside or terraced fields. This intelligent design prevents the rapid loss of body heat and humidity, promoting a more comfortable and healthy cooling sensation. With an impressive 100 adjustable gears for wind speed and a 24-hour preset timing function (with specific timing options ranging from 2 to 7.5 hours), users gain precise control over their airflow. The MI HOME app further enhances this customization, allowing for the DIY creation of unique natural wind curves, where cycle period and wind speed can be tailored to individual preferences for a truly personalized cooling experience.
• Exceptional Energy Efficiency and Whisper-Quiet Operation: At the heart of the MIJIA Tower Fan 2nd is a Smart DC Frequency Conversion Motor, engineered for optimal energy conservation. This advanced motor allows the fan to operate with a power consumption as remarkably low as 1.5W, leading to significant reductions in electricity bills. Despite its powerful air volume, which can reach up to 494m³/h, the fan maintains an incredibly low noise profile. In its lowest direct blow setting, the operating sound is a mere 28.7dB(A), ensuring an undisturbed environment for sleep, study, or work. Even when delivering maximum air volume, the noise level remains a moderate 59.7dB(A), well within comfortable listening thresholds.
• Comprehensive Child Safety and Seamless Smart Home Integration: Prioritizing the safety of your loved ones, this fan is thoughtfully designed with multiple child protection features. It boasts a fine 6.9mm air outlet grille, specifically engineered to prevent curious little fingers from entering. The robust ABS shell ensures stable and safe operation, while the power adapter outputs a safe 12V voltage, mitigating electrical risks. A dedicated Child Lock function further prevents accidental adjustments by children. Beyond safety, the fan offers seamless integration into your smart home ecosystem through MI IoT Smart linkage. This allows for intelligent automation, such as automatically activating the fan when the indoor temperature surpasses 27°C or deactivating it when it drops below 18°C, enhancing overall home comfort and energy management.
• Sleek, Space-Saving Design and Effortless Maintenance: The MIJIA Smart DC Frequency Conversion Tower Fan 2nd features a slender, cylindrical tower design that not only looks modern but also occupies minimal floor space, with a base area roughly the size of an A4 paper. This elegant form factor allows it to blend effortlessly into various home decors without being obtrusive. Thoughtful design elements include conveniently placed top control buttons for easy manual operation and an indicator light that automatically dims or turns off in sleep mode to avoid disturbing rest. For hygiene and longevity, the fan is engineered for easy maintenance, featuring a 4-step quick disassembly process that simplifies the cleaning of the impeller and rear grille, ensuring a continuous supply of fresh, clean air.
