It uses ultrasonic mist technology to add fine moisture to the air, helping reduce dryness that can cause irritated skin, dry throat, and breathing discomfort.

It features smart Wi-Fi control via the VeSync app, allowing you to adjust humidity settings, schedule operation, and monitor conditions remotely.
