Humidifier with removable locator module

A water vapor filtration and delivery system comprising:

• a water inlet configured to be coupled to a source of water;
• a pump for pumping an amount of water from the water inlet;
• a filtration unit connected to the water inlet that removes all contaminants larger than 50 nanometers;
• a nozzle for distributing filtered water vapor into a stream of air, wherein the nozzle comprises an outlet orifice;
• a locator module coupled to a wall of an air duct that is part of a ductwork system of a building, the locator module comprising a base plate fixedly attached to the wall of the air duct, a locator plate removably attached to the base plate, and at least one hand bolt;
• a flexible hose between the filtration unit and the locator module configured to transfer water from the filtration unit to the locator module;
• a rigid pipe between the locator plate and the nozzle;
• and
• wherein the rigid pipe extends at least from the wall of the air duct to approximately a center of a perpendicular cross-section of the air duct such that the nozzle is rigidly positioned within a center portion of the air duct and configured and positioned to provide water through the nozzle in line with a direction of airflow of air moving through the air duct.
