Fogging nozzles produce droplets in the range of 5-50 microns, which are very fine and almost invisible to the naked eye. These nozzles are typically used for humidification, odor control, and dust suppression applications. Fogging systems are also used in greenhouses to create a highly humid environment that is ideal for plant growth.

On the other hand, misting nozzles produce droplets in the range of 50-100 microns, which are slightly larger than the droplets produced by fogging nozzles. These nozzles are used for cooling applications, such as outdoor patios, restaurants, and theme parks. Misting systems can also be used for dust suppression, odor control, and humidification.
