This tower fan stands out with quiet operation, thanks to its high-quality DC motor that ensures low noise at all speeds-even in sleep mode, the noise level stays as low as ≤60dB, letting you enjoy coolness without disrupting a peaceful sleep environment. It also enables rapid cooling: equipped with an extra-large fan wheel and dual humidifying curtain design, it reaches a maximum wind speed of 23.3ft/s, quickly expelling heat from the room for instant cool comfort. For long-lasting use, the standing fan comes with a 4L large-capacity water tank to meet extended-hour needs, and it supports ice crystal holders to accelerate cooling, ensuring lasting coolness throughout summer. Additionally, its 70° wide oscillation range (as an oscillating fan) ensures cool air covers every corner of the room, eliminating uneven cooling for consistent comfort across the entire space. It's also convenient and easy to use: the bedroom fan offers multiple modes via one-touch control (Baby Mode, Comfort Mode, Strong Mode, Smart Mode), plus the flexibility of both touch and wireless remote control, along with a 24-hour timer function to suit diverse usage needs.
