The sleek BreatheFrida 3-in-1 Humidifier by Fridababy creates a calming, comfortable atmosphere in the nursery. This half-gallon, filter-free humidifier uses ultrasonic vibration to produce a gentle, cool mist for up to 12 hours. Adding a few drops of an aromatherapy-grade essential oil creates a soothing experience for little ones by safely scenting the room with your favorite aroma. At night, the device lights up in soothing tones of blue, green or purple. Each function runs independently or together to create a relaxing environment for sleep or quiet time.
