AAF International has launched the BioShield air filtration line to help swine and poultry producers mitigate the spread of airborne viral pathogens. The systems, available in MERV 15 and 16 ratings, are designed to combat increasingly virulent outbreaks like PRRS and HPAI that threaten herd viability.
Why it matters
Producers face rising mortality rates and significant production gaps from viral outbreaks, making barn-level biosecurity a critical component of maintaining operational continuity. These filtration systems provide a mechanical defense against pathogens that can otherwise force costly total depopulation.
University of Minnesota research confirms filtered sow farms achieve 51% to 58% lower PRRS outbreak rates compared to unfiltered sites over 16 years. During severe outbreaks, newer strains can cause mortality rates of 50 to 60 sows per day, potentially forcing producers to depopulate.
The players
AAF International
A global manufacturer of air filtration solutions specializing in industrial, commercial, and agricultural clean-air systems.
University of Minnesota
A public research university providing data on animal health, disease transmission, and biosecurity protocols for the agricultural sector.
The details
The BioShield series allows producers to customize air intake configurations by mixing 12-inch and 17-inch filter sizes with varying MERV ratings to suit specific barn ventilation designs. By capturing airborne particles before they enter the production environment, the systems aim to prevent the introduction of pathogens. This helps operators avoid severe production gaps that, in worst-case scenarios, can extend until November.
Timeline
2026: The product series will be featured at the World Pork Expo in Des Moines.
November 2026: This represents the potential duration of production gaps for producers affected by active outbreaks.
Market Landscape
The introduction of BioShield reflects the industry's response to the heightened virulence of PRRS and HPAI, which have forced a shift toward more rigorous barn-level containment. This development follows a period where pathogen-driven mortality has necessitated a rethink of standard biosecurity precedents.
Producers should evaluate current ventilation systems against these high-efficiency MERV ratings to determine if retrofitting can reduce the risk of catastrophic herd loss. Operators should also review the long-term cost of production gaps compared to the capital expenditure required for upgraded filtration.
The takeaway
Filtration serves as a crucial mechanical barrier in modern barn biosecurity, directly impacting the ability to avoid mass depopulation during viral spikes. Operators should prioritize tracking local outbreak trends to determine if high-efficiency filter upgrades are necessary for safeguarding seasonal production cycles.
What happens next
The BioShield product series will be presented at the World Pork Expo in Des Moines during 2026.
