This is a godsend when you have a head cold. It is small, easy to clean and only takes a small amount of water. It is steam, so if you are using with a small child, I would ensure it is set on a table and you are holding it for them. The steam does not come out like it would if it was a face steamer — it is a slow and steady stream. It makes you feel like your nose and lungs just got out of a hot and steamy shower, but you can use it anytime you want!
