Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.

In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

The recent shift in commercial swine breeding-gestation-farrowing facilities to incorporate filtered ventilation systems raises numerous questions about system performance and longevity of filters. It has been shown that air filtration with ASHRAE standard MERV 14, 15 and 16 type filters are effective at reducing the aerosol spread of PRRSV and Mycoplasma hypopneumonia. The areas that are lacking in current literature is relevant filter testing methodology and criteria for determining filter end of life in an agricultural setting. To address this, a mobile air filter testing unit (MAFT) was developed to address the testing needs for the swine industry to evaluate on-site filter performance. The test duct is capable of measuring pressure drop and airflow for a pre-filter and main V-bank filter combination. The unique feature of this system is the ability to test filters on site and to test the same filter at different points in time. It was shown through validation that MAFT was accurate at measuring the airflow through the filter combinations in comparison to an ASHRAE 52.2 standard lab
