1. A cartridge for a vaporizer device, the cartridge comprising:
a reservoir housing configured to hold a vaporizable material, the reservoir housing comprising one or more vents configured to allow the passage of air into the reservoir housing to maintain an inner pressure of the reservoir housing;
an airflow tube extending through the reservoir housing, the airflow tube defining a passageway extending therethrough; and
a combined wicking and heating element disposed within the passageway way of the airflow tube, the combined wicking and heating element configured to draw vaporizable material directly from the reservoir housing and vaporize at least a portion of the drawn vaporizable material into vaporized material;
wherein the combined wicking and heating element has a capillary path that extends along a first dimension of the combined heating and wicking element, and an electrical path that extends along a second dimension of the combined wicking and heating element, wherein the first dimension is different than the second dimension.
