  • Patent number: 11959661
    Abstract: A water vapor filtration and delivery system having a water inlet 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, and a nozzle having an outlet orifice for distributing the filtered water vapor into a stream of air. The water vapor filtration and delivery system includes a locator module coupled to a plenum or a wall of an air duct and having a base plate attached to the plenum, a locator plate removably attached to the base plate, and at least one hand bolt. There is a flexible hose between the filtration unit and the locator module configured to transfer water from the filtration unit to the locator module and a rigid pipe between the locator plate and the nozzle.

  • Patent number: 10871297
    Abstract: A humidifier is provided that typically includes a water filtration unit and a pump that draws filtered water from the water filtration unit, typically a carbon nanotube filter. The humidifier further includes a nozzle having an outlet orifice, wherein the nozzle is connected to the pump, where the pump forces the filtered water through the nozzle, thereby expelling the filtered water into an atmosphere in the form of a purified vapor or mist.

  • Patent number: 8978683
    Abstract: A method of reducing the downward flow of air currents on the leeward side of an emissions emitting structure including the step of using a system that includes components chosen from the group consisting of one or more mechanical air moving devices; physical structures; and combinations thereof to create an increase in the air pressure within a volume of air on the leeward side of an emissions emitting structure having emissions that become airborne. The increased air pressure prevents or lessens downward flow of emissions that would occur without the use of the system and increases the safety by which one can travel a road or other transportation route that might otherwise be visually obscured by the emissions and the safety of the property and those within the area where emissions occur.
