Abstract: A ventilation element attachable to a lower portion of a sectional garage door for enabling a ventilation condition of the garage door in a partially open position. The ventilation element provides a peripheral frame dimensioned and shaped to mimic a lower section of the sectional garage door. The peripheral frame enables a plurality of filters to be removably nested therein. The peripheral frame is movably attached to the interior surface of the garage door by a plurality of travel bars fixed thereto; a complementary number of grip brackets are attached to the peripheral frame so that the peripheral frame is moveable between a retracted position and an extended position disposing the peripheral frame below a bottom elevation of the garage door so that when the garage door is in the partially open position, the peripheral frame and nested filters established a ventilation barrier between the garage door and the driveway.

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.
