The present invention provides exhalation purification that provides the ability to capture, isolate, deliver and/or destroy airborne pathogens and pollutants faster than currently used HVAC systems, HVAC purification systems, and/or HVAC air conditioning systems are capable of unit and/or system. By way of non-limiting example, airborne pathogens can travel long distances while remaining suspended within a building for 15 minutes or more before being captured by HVAC return systems. This is especially true for auditoriums, theaters and schools. It is estimated that 70% of the day at school is spent sitting at a desk or table. As with auditoriums, theaters, and school classrooms, the nearest HVAC air return unit is often located at a remote location in the room where the individual is sitting. Thus, the exhaled breath of many individuals travels in the air across rows of seats, desks and/or tables before it is captured within the HVAC air return devices.

Many schools and universities are now adding additional airflow filters and/or upgraded HEPA filters to their air conditioning systems. While this may help to some extent in reducing pathogen transmission, it does not adequately or sufficiently meet the requirements. Simply upgrading the HVAC system does not significantly reduce the potential for airborne transmission of pathogens inside a building or vehicle environment. There is an urgent need to capture and isolate the exhaled breath of an individual much closer to that individual. By doing so, it is possible to significantly reduce the cubic area and diameter of cone-shaped exhaled breath from an individual and capture and/or isolate most of it.

Aerosol dispersions, which carry several viruses, including the coronavirus (“COVID”), occur when a person exhales, speaks, shouts, coughs, and sneezes. Under normal circumstances, exhaled breath is known to form a cone as it exits an individual's mouth and nose. Normally, the cone of exhalation from the nose and mouth is about 55 mm in diameter. From here, it usually (but not always) spreads outward at an angle of 22 to 33 degrees, with a downward central trajectory of 10 degrees. The louder the noise a person makes with their voice, lungs, throat or mouth, the farther the viral or bacterial aerosol will generally travel through the air. Recent studies have shown that aerosols containing airborne viruses can remain airborne for up to 15 minutes in a confined, confined environment. Research has shown that COVID aerosols can spread up to 3 meters or more through singing, shouting, coughing and sneezing. By way of non-limiting example, COVID 19, strains of COVID, coronavirus, measles, mumps, SARS, smallpox, common cold, influenza, and tuberculosis can be transmitted through the air. The closed, narrow indoor environment with multiple seats is very vulnerable to the spread of the coronavirus. There is a need to capture, isolate and purify an individual's exhaled breath much faster than is currently being done.

In embodiments of the invention, an exhalation purification system may include a plurality of exhalation collectors networked to one or more remote exhalation purification chambers. The exhalation purification unit may include an exhalation collector and an exhalation purification chamber. The exhalation purification unit may be mobile, such as, but not limited to, from one table top to another table top, from one desk to another desk, from the back of one chair or seat to the back of another chair or seat, or any combination thereof. It is possible to move in shape. The exhalation purification unit is stationary and may not be moved. The exhaled breath collector may be located on a desk top or table top, attached to the seat back, incorporated into the seat back, or spaced a distance back from the seat back. The seat back may be formed or molded to be an exhaled breath collector. Most, but not all, exhaled breath collectors may include an open front.

The exhalation collector may include an inner back recessed exhalation barrier surface. The exhaled air catcher may include an optional exhaled air catch basin. The exhaled breath collector collects a significant amount of exhaled breath from the individual sitting in front of the exhaled breath collector and moves the collected exhaled breath into the exhaled breath purification chamber or permits the movement of the exhaled breath to be purged, filtered, purified, or any combination thereof. designed to be In some embodiments, the exhaled breath travels with or is allowed to travel with air from a location where the individual is sitting or standing.

In some embodiments, the exhalation collector may include an internally recessed exhalation barrier surface. However, in certain embodiments the exhalation collector may not have such a recessed exhalation barrier, and the rear of the exhalation collector may open into an exhalation purging chamber which may be of the same overall size. In this case, air inlets may be formed on the side of the exhalation purification chamber common to the exhalation collector, and air outlets may be formed on the side of the exhalation purification chamber common to the corresponding place environment. In other particular embodiments, the air inlet side of the exhalation purification chamber may fill part or all of one or more of the top, side, bottom or rear side of the exhalation collector. The design of the exhalation collector, exhalation purification chamber and/or exhalation purification unit depends primarily on the place of use.
