Abstract: A system for filtration for livestock comprises a barn enclosure including a surrounding wall and a ceiling; the enclosure being sized to house livestock; the barn enclosure having a positive internal pressure differential compared to ambient air. An air inlet is in communication with an interior of the barn enclosure; the air inlet drawing in ambient air. A filter arrangement is downstream of the air inlet, cleaning the drawn in ambient air from the air inlet. A conduit having an air vent arrangement is in air flow communication with the filter arrangement and allowing the filtered air to flow through the vent arrangement into the interior of the barn enclosure. An air exhaust is arranged to exhaust air from the interior of the barn enclosure.
