1. A method for mitigating airborne pathogens from a livestock house, said method comprising:
using a cross-flow ventilation system, which is fluidly connected to the livestock house comprising two parallel sidewalls and two end walls that are parallel to each other and perpendicular to said sidewalls to form a tunnel section of said livestock house, wherein the two parallel sidewalls are longer than the two end walls and the cross-flow ventilation system is configured to control air quality and movement by:
introducing ambient air into at least one air filtration system that includes one or more multistage filters and that is attached to a sidewall of the two sidewalls of the livestock house;
conditioning the ambient air in said at least one air filtration system by performing at least one step selected from filtering, cooling, disinfecting, or pressurizing said ambient air to form conditioned air;
introducing the conditioned air into an air chamber that extends at least 60% of a length of at least one of the two parallel sidewalls;
flowing the conditioned air from the air chamber into the livestock house through at least one ventilation panel to an opposing sidewall of the two parallel sidewalls with a laminar or substantially laminar flow of air; and
removing exhaust air from the livestock house using an exhaust fan attached to the opposing sidewall opposite the at least one air filtration system.
