Non V-bank filter for animal confinement facility
First Claim
1. A filter element adapted for filtration of porcine reproductive and respiratory syndrome virus (PRRSV) from an air flow stream to an animal confinement building, the filter element comprising:
- a rectangular frame;
a filter media pack extending across the frame in a non-V-bank configuration, the filter media pack having a depth of less than 8 inches such that in combination with the frame the filter element has a depth of less than 10 inches in a direction perpendicular to a plane defined the rectangular frame, the filter media pack comprising;
a MERV rating of at least 14 and a filtration efficiency sufficient to prevent transmission of the PRRSV; and
an air flow capacity of greater than 200 cfm @ resistance of 0.2 inch water gauge, per square foot occupied by the filter element transverse to the air flow stream.

Abstract
A non-V bank filter for an animal confinement application such as for filtering out the porcine reproductive and respiratory syndrome virus (PRRSV) is provided. The filter may be a deep pleat of synthetic filter media with at least a MERV 14 rating and efficiency sufficient to filter out the PRRSV in high air flow applications. The media may be embossed and have spacers to provide for structural support and open filter structure for airflow. The filter can occupy less space and in some embodiments ½ or even less space than a corresponding V-Bank filter with comparable performance.
