The present disclosure is directed to a novel redesigned or retrofitted cabin air filtration system utilizing an ultraviolet light, radiation, or an energy matrix membrane and related technology to eliminate toxins such as viruses, bacteria, mold, fungi, rickettsia, protozoa, etc. from the air system in a vehicle, such as an automobile, marine vehicle airplane, etc., thereby improving the current cabin air filter functionality and providing a sterile air distribution environment throughout the cabin of the vehicle or small area.

This present application discloses use of a hydrogen peroxide solution for a filter media cleaning and sanitizing system which is designed to dispense the solution to disinfect an air filter. The system is attached to an existing air filter, allowing the system to lightly mist the filter media with the solution. The invention also adjusts the ions in the air system to eradicate germs, bacteria, viruses, and other airborne pathogens, and functions as a sanitization method for any type of air or HVAC system.

A system is described to protect a person from exposure to pathogens in breathing. A control device which can be an adjustable or removable filter, a valve to switch air sources, added substances interruption of the air stream is controlled by a determination made by a machine learning system with a machine learning model usually implemented as a neural network. The determination is made on the basis of training of the model which can be one or multiple stages with one stage in a large server not in real time and another stage in a field device which uses sensors and other information sources to acquire data to make a decision concerning the relative risk of various circumstances. Conditions detected include presence of other persons, level of activity of the protected person and many other factors concerning the surroundings, activity and history of the protected person.

Hygiene regulations and social distancing are very effective in blocking short distance infections. During the lockdown, the distance rules can usually be adhered to, but what happens when the actual lockdown is over and the people meet again in a confined space? Then additional effective and efficient protection is essential to stabilize infection rates. Since the viruses are spread by contact and droplet infection, technical devices are required that effectively intervene in the chain of infection and effectively block infection. An effective protection is the respiratory mask as known since 100 years. An alternative to mask is an aerosol protection system for various applications in environment. The protection system consists of adjustable air sucking device and air blowing device in different form factors based on application. The aerosol protection system uses either an air curtain or air shield to prevent the aerosol going from one side of the curtain or shield to the other side.

An apparatus for irradiating air flow in a vehicle includes a filter unit configured to couple to a recirculating-air conduit connected to a manifold of an air circulation system, the filter unit having an inlet end, and a filter disposed in the inlet end of the filter unit, including an outer wall of filter media having a shape that defines an interior volume of the filter. The apparatus further includes an ultraviolet light disposed on an end plate, configured to be mounted with the ultraviolet light positioned in the interior volume of the filter and the end plate against an open end of the filter. The ultraviolet light is configured to emit ultraviolet radiation substantially at between 222 nm and 265 nm for irradiating air flow through the filter into the air circulation system.

A filter assembly including a plurality of filter modules, wherein each filter module in the plurality of filter modules includes a frame, a filtration element coupled within the frame, and at least one mating feature. The at least one mating feature of each filter module is configured for selective engagement with the at least one mating feature of another filter module such that the plurality of filter modules are coupled together in a serial arrangement.

A system for providing a centralized aerosol source extraction and filtration system is disclosed. The system includes an aerosol capture component coupled to a set of aerosol capture ductwork being located at or near a patient's mouth while treatment is being provided and is coupled to a set of aerosol capture ductwork, a filter and fan component coupled to the set of aerosol capture ductwork for generating the necessary pressure differential to draw the air about the patient's mouth into the aerosol capture component along with any airborne particulates, contaminants, and pathogens, and a recycled clean air component for returning recycled clean air back to patient areas and workspaces through a set of recycled clean air ductwork arranged to create positive and directional airflow throughout the office space. The filter and fan component has one or more filter layer types to remove particulates, contaminants, and pathogens from an air flow received from the set of aerosol capture ductwork.
