A device and method for delivering an aerosolized liquid having therapeutic properties to a user's lungs. The compact and convenient device includes a housing of such size that it can be held in a user's one hand with an exit opening in the housing for directing the aerosol to the user's mouth. The housing encloses a dispensing system for containing the liquid to be aerosolized and delivering it to an electrohydrodynamic apparatus and an electrohydrodynamic apparatus for aerosolizing the liquid and delivering the aerosol to the exit opening. The electrohydrodynamic apparatus produces a cloud of aerosolized liquid droplets having a monodispersed reparable droplet size and near zero velocity. The aerosolizing apparatus includes a plurality of spray sites each having a tip end, the spray sites cooperating with a charge source to result in an aerosolized spray from at least one tip end, a plurality of discharge electrodes downstream of the tip ends, and a plurality of reference electrodes downstream of the plurality of discharge electrodes.
