I really love my Blue/White Crane Droplet Humidifier. It is filter-free ultrasonic that I don't need to change every time. It has a clean control anti-microbial function that helps me lessen the cleaning time, specially that I have a toddler that always on the go. It has a beautiful design, it whisper quietly and it has a right size for our room. It helps us (my sons and me) to get rid of nasal congestion, sinus irritation, coughs that causes the dry air. We always have a good night sleep since we got this Crane droplet humidifier. I definitely recommends it to all the moms like me who wants to have their own humidifier.
