    Ultrasonic Humidifiers

    Ultrasonic humidifiers are also a type of cool mist humidifier. They use high-frequency sound vibrations or a nebulizer to break the water into droplets, which are then propelled into the air with a fan or other mechanism.

  • Evaporative Humidifiers

    Evaporative humidifiers are a type of cool mist humidifier, meaning the mist emitted from the humidifier is room temperature to cool. They work by speeding up the process of natural evaporation.

  • Warm Mist Humidifiers

    Warm mist humidifiers differ from evaporative and ultrasonic humidifiers because they produce (as the name suggests) a warm mist in the form of steam.
