THE BEST HUMIDIFIER FOR YOUR BABY! BPA-free, and SO QUIET. Some humidifiers rattle, or hum, or make strange slurping noises—how can baby (or you!) sleep through that. At under 21dB, the Levoit Classic 100 is quieter than a whisper—and any other leading humidifier. Also, you and your baby will love the soft, soothing NIGHT LIGHT; which you can switch off if you prefer.
CUSTOMIZE YOUR MIST. Direct the 360-degree rotating head wherever you like, and select your preferred mist level with the simple control dial. Create the ideal indoor climate for the nursery, the family room, your bedroom, everywhere. A single unit will humidify up to 290 square feet.
24-HOUR CONVENIENCE, AUTO SHUT-0FF. The oversized 2.4L tank delivers hassle-free humidifying all day and all night, and automatically shuts off before it runs dry. Just fill, turn it on, and breathe easy.
