Aspects of the present disclosure provide for a portable airborne pathogen control apparatus configured to be selectively positioned within an interior room and configured to enable a floor-to-ceiling flow of air within the interior room. The portable airborne pathogen control apparatus may comprise a housing with an air intake disposed at a lower area of a base housing and an air outlet disposed at an upper area of an elongated duct extending from the base housing. A blower fan housed within an interior chamber of the housing may be configured to direct a floor-to-ceiling flow of air through the interior chamber from the air intake to the air outlet. A volume of air directed through the interior chamber of the housing may be disinfected using one or more UV-C emitters and/or cold plasma generator(s) housing in the interior chamber of the housing. ## Claims ### Claim 1 A wall-integrated airborne pathogen control apparatus, comprising: a housing configured for installation within a wall between studs and having a room-side intake vent positioned adjacent a floor of a room and a room-side discharge vent positioned adjacent a ceiling of the room, the intake vent and discharge vent defining a floor-to-ceiling airflow path through the housing; a blower disposed in the housing and configured to drive air from the intake vent to the discharge vent; a filter disposed along the airflow path, the filter comprising a HEPA filter; at least one UV-C emitter disposed along the airflow path and configured to irradiate air within the housing; and a cold-plasma generator disposed along the airflow path. ### Claim 2 (depends on 1) The wall-integrated airborne pathogen control apparatus of claim 1 wherein the housing has a profile depth in the range of 3 inches to 12 inches. ### Claim 3 (depends on 1) The wall-integrated airborne pathogen control apparatus of claim 1 wherein the housing is configured to be removably received in a wall sleeve anchored to studs spaced in the range of 16 inches on center to 24 inches on center. ### Claim 4 (depends on 3) The wall-integrated airborne pathogen control apparatus of claim 3 further comprising vibration isolation mounts between the housing and the wall sleeve and closed cell gaskets that air seal the wall sleeve to the wall. ### Claim 5 (depends on 1) The wall-integrated airborne pathogen control apparatus of claim 1 further comprising a prefilter disposed upstream of the HEPA filter, the prefilter having a MERV 8-11 rating. ### Claim 6 (depends on 1) The wall-integrated airborne pathogen control apparatus of claim 1 wherein the HEPA filter is H13 or H14 and includes peripheral gaskets that limit bypass leakage to ≤0.5% at rated flow. ### Claim 7 (depends on 1) The wall-integrated airborne pathogen control apparatus of claim 1 wherein the cold plasma generator is a dielectric barrier discharge device and the controller limits plasma duty cycle to maintain ozone below 0.05 ppm. ### Claim 8 A wall-integrated airborne pathogen control apparatus, comprising: a housing configured for installation within a wall and having a room-side discharge vent, an exterior-side fresh-air intake port, and an exterior-side exhaust port; a blower disposed in the housing and configured to move air from the fresh-air intake port through the housing to the room-side discharge vent; a filter disposed along the airflow path, the filter comprising a HEPA filter; at least one UV-C emitter and a cold-plasma generator disposed along the airflow path; a first motorized damper coupled to the fresh-air intake port and a second motorized damper coupled to the exhaust port; a pressure sensor configured to measure a pressure differential between the room and an adjacent space; and a controller operatively coupled to the blower and to the first and second motorized dampers and configured to modulate at least one of blower speed and damper positions to achieve a target pressure differential. ### Claim 9 (depends on 8) The wall-integrated airborne pathogen control apparatus of claim 8 further comprising a cleanable outdoor prefilter at the fresh air intake port. ### Claim 10 (depends on 8) The wall-integrated airborne pathogen control apparatus of claim 8 wherein the controller modulates the first motorized damper to blend fresh air in the range of about 10% to about 40% of the total supply flow to the room. ### Claim 11 (depends on 8) The wall-integrated airborne pathogen control apparatus of claim 8 wherein the target pressure differential is a positive pressure between +0.5 Pa and +5 Pa relative to an adjacent corridor under a PID control loop using the pressure sensor. ### Claim 12 (depends on 8) The wall-integrated airborne pathogen control apparatus of claim 8 wherein the target pressure differential is a negative pressure between −0.5 Pa and −5 Pa when the controller commands the second motorized damper to a greater open area than the first motorized damper. ### Claim 13 (depends on 8) The wall-integrated airborne pathogen control apparatus of claim 8 further comprising a CO2 sensor, wherein the controller increases the fresh air fraction when room CO2 exceeds a threshold. ### Claim 14 (depends on 8) The wall-integrated airborne pathogen control apparatus of claim 8 further comprising an optional heat or energy recovery core (HRV/ERV) arranged to exchange heat between the exhaust and the fresh air intake. ### Claim 15 A wall-integrated airborne pathogen control apparatus, comprising: a housing configured for installation within an interior wall and having a room-side intake vent and a room-side discharge vent; a blower disposed in the housing and configured to draw air from the room-side intake vent through the housing and expel air via the room-side discharge vent; a filter disposed along the airflow path, the filter comprising a HEPA filter; at least one UV-C emitter and a cold-plasma generator disposed along the airflow path; a first motorized interior damper disposed upstream of the blower and a second motorized interior damper disposed downstream of the blower, each configured to regulate a respective flow opening to the room;
