A filter assembly including a rectangular inlet frame having a rectangular inlet opening to receive a primary filter and optional a prefilter. The filter assembly may include a rectangular outlet frame and a housing body that is collapsible to have a flattened shipping state and an erect state. The rectangular inlet frame may also be used as a housing by itself to support and house primary filters and prefilters. A gridwork including one or more grid dividers may be used in the rectangular inlet frame to provide 2 or more openings for receipt of filters.

1. An animal confinement facility comprising: an animal confinement building having: a ventilation system with an air flow inlet into an enclosure of the animal confinement building; anda structural frame of the building having a rectangular opening for flow through the air flow inlet;a molded plastic frame mounted to the structural frame and sealed thereto by a seal member located between the molded plastic frame and the structural frame;a primary filter mounted to the molded plastic frame arranged to filter air flowing through the air flow inlet;a peripheral seal between the primary filter and the molded plastic frame; androtatable clips mounted to the molded plastic frame, the clips securing the primary filter in the molded plastic frame and compressing the primary filter against the frame to compress the peripheral seal into sealing engagement therebetween. 2. The animal confinement facility of claim 1, further comprising an evaporative cooling bank downstream of the air flow inlet, a plurality of molded plastic frames being mounted to the structural frame and sealed thereto at a location between the air flow inlet and the evaporative cooling bank, a plurality of primary filters mounted into the molded plastic frames wherein the primary filters filter the air prior to the evaporative cooling bank. 3. The animal confinement facility of claim 2, wherein the evaporative cooling bank comprises a evaporative pad extending vertically and a water recirculation system flowing water over the evaporative pad. 4. The animal confinement facility of claim 1, wherein the primary filter has a rating of MERV 14 or higher and an efficiency sufficient to adequately filter the PRRSV, and is configured to filter sub-micron sized viruses from an airflow stream flowing through the air flow inlet. 5. The animal confinement facility of claim 2, further comprising a pre-filter arranged upstream of the primary filter, and having a lower efficiency than the primary filter, the pre-filter being rated at a MERV 14 or lower, the pre-filter adapted to filter dust to prevent premature clogging of the primary filter. 6. The animal confinement facility of claim 1, wherein the molded plastic frame is sealed to the structural frame with a caulk bead. 7. The animal confinement facility of claim 1 wherein the molded plastic frame is sealed to the structural frame by a sealing gasket mounted either to the structural frame or assembled to the molded plastic frame. 8. The animal confinement facility of claim 1, wherein the primary filter comprises at least one of a V-bank filter and a rectangular filter that includes filter media that is at least 3 inches deep, and further comprising a prefilter upstream of the primary filter. 9. A filter system, comprising: a plurality of plastic inlet frames, each inlet frame having at least one inlet opening and a recess with a seating surface in surrounding relation to the inlet opening, the plastic inlet frames mounted in an array to a wall frame in a building;a plurality of primary filters comprising at least one of a V-bank filter and a rectangular filter that includes filter media that is at least 3 inches deep;each primary filter having an outer peripheral flange seated against the seating surface and extending through the inlet opening; anda plurality of pre-filters upstream of the primary filters, each pre-filter seated against an upstream face of the outer peripheral flange of a corresponding primary filter;a first set of retainers mounted on each plastic inlet frame, the retainers adapted to secure the primary filters along the seating surface of each plastic inlet frame;a second set of retainers mounted on each plastic inlet frame securing the pre-filters over the primary filters andeach retainer rotates about a corresponding axis of rotation that is perpendicular to the seating surface of the corresponding plastic inlet frame. 10. The filter system of claim 9, further comprising sealing gaskets sealing between each plastic inlet frame and the wall frame. 11. The filter system of claim 9, wherein the plastic inlet frame is molded from at least one of high-impact polystyrene and ABS plastic. 12. The filter system of claim 9, wherein the plastic inlet frame is molded from one of high-density polyethylene and high molecular weight polyethylene. 13. The filter system of claim 9, wherein each plastic inlet frame includes at least two separate inlet openings, the inlet openings between divided by gridwork, wherein each inlet frame is adapted to hold multiple ones of the primary filters. 14. The filter system of claim 13, wherein the inlet openings are each 24 inches by 24 inches, or 20 inches by 24 inches. 15. The filter system of claim 9, wherein the plastic inlet frames are secured to the wall frame with screws. 16. The filter system of claim 9, wherein the wall frame includes vertical studs and horizontal cross-braces assembled between the vertical studs, and wherein the sides of the plastic inlet frame is attached to the vertical studs, and the top and bottom of the plastic inlet frame is attached to the horizontal cross-braces. 17. The filter system of claim 9, wherein the primary filter has a rating of MERV 14 or higher and an efficiency sufficient to adequately filter the PRRSV, and is configured to filter sub-micron sized viruses from an airflow stream flowing through the air flow inlet. 18. The filter system of claim 9, wherein the wall frame is provided by an animal confinement building having a ventilation system with an air flow inlet into an enclosure of the animal confinement building; and further comprising an evaporative cooling bank downstream of the air flow inlet, the plastic inlet frames being mounted to the structural frame and sealed thereto at a location between the air flow inlet and the evaporative cooling bank, a plurality of primary filters mounted into the plastic inlet frames wherein the primary filters filter the air prior to the evaporative cooling bank. 19. The animal confinement facility of claim 18, wherein the evaporative cooling bank comprises a evaporative pad extending vertically and a water recirculation system flowing water over the evaporative pad. 20. The filter system of claim 10, further comprising a peripheral seal between each of the primary filters and the corresponding plastic inlet frame.
