Have been using this product for years. This is my third unit. Very useful for traveling and even a small bedroom next to your bed, can give you relief and humidity. It is a major pain to clean. However, best way I found so far is to use a water pick type device to clean the nozzle. Also be very careful when you attach the water bottle as it can easily break the connection nozzle
