Comes in 1 liter container good for producing more than 3 hours of fog.
NOTE: It is possible that the small water-based particles can set some types of smoke detectors off. Usually, this is only a problem with optical type detectors, because they sense these particles as smoke. We suggest running a test with the fog machine when used indoors to see if this is a problem. Sprinkler systems on the other hand are usually triggered by heat, so the fog in the air won't active heat-activated sprinkler systems.
