The invention is directed to an electromagnetic air filtration system and process for removing charged pathogens, such as, the SARS-CoV-2 virus, from an air stream. The air filtration system and process provide a magnetic field within an airflow to remove charged pathogens from the airflow, thereby producing treated air.

An air purification unit and/or system for an environment with multiple seated individuals, including an air collector and air purification chamber, to be used independently from or in conjunction with the environment's air handling system.

Systems and methods provide airflow to a first area from a second area within a vehicle. The system includes a fan mounted within a door separating the first area from the second area. The fan is configured to direct airflow from the second area into the first area. The fan having a shield positioned adjacent to the second area that is configured to conceal the fan.

Within examples, a system to provide filtered air to an enclosure for a passenger of a vehicle is described that includes a collapsible canopy hood attachable to a support structure of a vehicle, and a filter unit mounted to the support structure of the vehicle and having an output coupled to the collapsible canopy hood. The filter unit includes an air filtration component to filter air that is then output to the collapsible canopy hood.

In some examples, an air treatment system includes a filter, an ozone sensor, and a separator configured to separate air into a nitrogen-enriched gas and an oxygen-enriched gas. The filter is configured to remove ozone from an air stream and supply filtered air to the separator. The ozone sensor is configured to sense an ozone level of the filtered air issuing from the filter prior to encountering the separator. The air treatment system may include processing circuitry configured to monitor the ozone level sensed. The air treatment system may be part of an inerting system configured to supply the nitrogen-enriched gas to an ullage space of a fuel tank.

An environmental control system is provided. The system includes a sorbent regeneration device. The sorbent regeneration device includes at least one regenerative sorbent material operative to remove gas substances from air. The at least one regenerative sorbent material is operatively coupled to a source of hot air. The sorbent regeneration device further includes at least two bypass valves that are operative to selectively direct some or all of the hot air into the at least one regenerative sorbent material. The environmental control system further includes one or more air quality sensors and a controller operatively connected to the at least two bypass valves and the one or more air quality sensors. The controller is operative to control one or more of the at least two bypass valves in response to air quality determined from the air quality sensors.

A vehicle includes a passenger cabin, a monument, a pet travel system, and a ventilation system. The pet travel system includes at least a portion of the monument and at least one pet storage module configured to be received in the portion of the monument. The ventilation system includes an inlet port defined in the at least one pet storage module, an exhaust port defined in the at least one pet storage module, and an exhaust duct. The inlet port is in flow communication with an air source outside of the pet travel system. The exhaust duct is in flow communication with the exhaust port. The pressure within the exhaust duct is lower than the pressure of the air source to cause air to flow from the air source through the at least one pet storage module from the inlet port to the exhaust port.

Disclosed is a valve assembly, having: a valve duct having an upstream end, a downstream end and a duct wall extending from the upstream end to the downstream end; a first conduit extending from a first end at the valve duct to a second end spaced apart from the first end, the first conduit terminating at a valve assembly component; and a washing filter that includes filer media, wherein the filter media extends into the valve duct to remove particles and provide a clean flow to the first conduit.

An air management system for a common indoor room or space that comprises a plurality of air outflow apertures or vents, a plurality of air curtains having at least a portion of the air curtains separated from one another, a plurality of separated air suction intakes, and an air sterilization and/or air cleaning mechanism.

An air purification unit and/or system for an environment with multiple seated individuals, including an air collector and air purification chamber, to be used independently from or in conjunction with the environment's air handling system.
