What size of particles should dust filters protect against in animal confinement buildings?

• A. 0.1 microns in diameter
• B. 0.3 microns in diameter
• C. 1.0 microns in diameter
• D. 2.5 microns in diameter

Answer: (B)

Dust filters in animal confinement buildings are designed to capture particulate matter that can have adverse effects on both animal and human health. The correct size of particles that these filters should protect against is 0.3 microns in diameter. This size is significant because particles of this diameter are particularly problematic; they can penetrate deep into the respiratory system and potentially affect lung function. Particulate matter that is 0.3 microns is typically considered the most penetrating particle size (MPPS), meaning that filters are most efficient at capturing particles of this size. This is critical in environments where animals are housed closely together, as airborne pathogens and allergens can impact animal welfare and productivity. In animal confinement settings, airborne dust can carry pathogens, respiratory irritants, and allergens, which underscores the importance of having effective filtration systems. Filters that target 0.3 micron particles can thus ensure a healthier environment for livestock and reduce the risk of respiratory issues associated with dust exposure.
