    About

    The Safety 1st IH166 is part of the Humidifiers test program at Consumer Reports. In our lab tests, Humidifier models like the IH166 are rated on multiple criteria, such as those listed below.

    Output: A high score means the device releases enough moisture to effectively humidify its claimed room size. A top-scoring model ensures sufficient output to improve humidity and comfort.

    Convenience: Convenience is the ease of operating and maintaining a unit.

    Noise: A high score means the unit operates at a very low noise level, barely louder than a hum. A top-scoring model runs quietly, making it less likely to disturb you, even while you sleep.
