An apparatus and method for introducing a liquid substance into air flowing into an environment includes a main container for containing a reservoir of the liquid substance, and exhaust fan for withdrawing air from within said container to thereby create a negative air pressure condition therein, an air intake port having an upper open end exterior of the container and a lower open end within the container and in close adjacent relationship to a top surface of the reservoir of liquid, and a resupply container connected to the main container and including a pump to resupply liquid to the main container. Operation of the exhaust fan creates an air flow through the air intake port, causing the stream of air exiting the lower open end to impinge upon and agitate the top surface of the liquid, resulting in evaporation of the liquid into the air in the container. The mixture of droplets/vapor and air in the container are removed by the exhaust fan and introduced into a stream of air flowing into a selected environment.
