The water usage of a mister for patio depends on several factors, including the type of mist, its settings, and how it is used. Different mister may have different mister patterns and flow control options that affect water usage. Some misters for backyard are designed to conserve water and can misting water in fine droplets or in an atomized form for more efficient coverage. These patio mist systems generally use less water.
