The Vicks Filtered Cool Mist Humidifier helps return essential moisture to dry air while providing soothing, invisible moisture for every day comfort.  With its self-regulating evaporative system, this humidifier adjusts output for maximum comfort while also preventing over-humidification of a room.  Designed with a break-resistant tank and an extra-wide opening, the Cool Moisture Humidifier is easier to fill and clean compared to other models. It also accepts two Vicks Scent Pads for long-lasting and soothing menthol vapors.
