Like fog, haze is made up of liquid droplets. Unlike fog, haze droplets are very fine and distributed evenly over a large area to form a mist. Some haze machines vaporize fluid by forcing it through a heater, while others use high air pressure to vaporize the fluid.

Haze is caused when sunlight encounters tiny pollution particles in the air. Some light is absorbed by particles. Other light is scattered away before it reaches an observer. More pollutants mean more absorption and scattering of light, which reduce the clarity and color of what we see.
