Methods, systems, and devices are described for creating a negative bias pressure within a liquid reservoir. Embodiments may include providing a liquid reservoir coupled with an aerosol generator. The liquid reservoir may be sealed to create the sealed reservoir. An ambient pressure may be maintained while the liquid reservoir is being sealed and the ambient pressure may be maintained in the sealed liquid reservoir until a portion of the liquid is dispensed. Further, embodiments may include vibrating the aperture plate to dispense the portion of the liquid. The portion of the liquid dispensed may decreases the amount of the liquid in the sealed reservoir. By decreasing the amount of liquid in the sealed reservoir, a negative bias pressure between an air side and a liquid side of the aperture plate may be created.
