We have the Crane Drop Ultrasonic Cool Mist Humidifier in blue. My son had a cough & wheezing at 3 months old. As a first time parent, that is nerve wracking! I used our Crane humidifier all through the night (yes! It ran all night!) & during every nap for about 6 days. I noticed improvement by the morning of day 2. I just pointed the spout in the direction of his crib. Very easy to clean and refill. Highly recommend! I love it! FIVE STARS FOR SURE!
