In its simplest form, misting systems incorporate a spray nozzle designed to produce water droplets smaller than the diameter of a human hair, even as small as 5 millionths of a meter. When water droplets this small hit the surrounding air they "flash evaporate", reducing the surrounding temperature as much as 35 degrees fahrenheit. This scientific principle, known as thermal dynamics, was the basis for the development of Arizona Mist.

Yes. The evaporative cooling concept will work ANY time you are able to achieve evaporation (See "How does mist work?"). The more complete the evaporation, the more effective the system will work. For areas with humidity above 80%, temperature reductions will be as high as 10 degrees. For humidity levels between 40% and 80%, temperature reductions will be as high as 20 degrees. Below 40% humidity, the temperature reductions may be as much as 35 degrees.

Because of the extremely small size of the nozzle opening (15 thousands of an inch!), some of the misting nozzles may eventually plug up. If this should occur, the nozzle should be removed and soaked in the Arizona Mist Nozzle Cleaner (See the bottle label for specific cleaning instructions). If the nozzle is not completely plugged, but simply sprays improperly, the entire mist line can be flushed with the nozzle cleaner for a preventative nozzle cleaning. The nozzle cleaner is safe for consumption, non-toxic and completely biodegradable. See the cleaner label for technical information.
