The Effects of Cage Design on Airborne Allergens and Endotoxin in Animal Rooms: High-Volume Measurements with an Ion-Charging Device

The use of filter tops on cages corresponds to a 50-fold reduction in mean levels of both airborne allergens (P < 0.001) and endotoxin (P < 0.001). The use of vented cages with filtered exhaust ports was associated with additional reductions. Animal Care Systems is the original direct-exhaust negative pressure IVC System with a filtered exhaust port.
