What are Bag In Bag Out (BIBO) Systems?
Bag In Bag Out (BIBO) Systems are specialized containment units designed to facilitate the safe removal and replacement of air filters in environments where hazardous particulates, pathogens, or toxic chemicals are present. The core principle of BIBO technology is to create a sealed, double-bagged barrier between the contaminated filter and the external environment during changeout procedures. This prevents the escape of hazardous materials and protects both personnel and facility infrastructure.
BIBO systems are engineered for use in applications with stringent contamination control requirements, including:
Pharmaceutical manufacturing cleanrooms
Biosafety laboratories (BSL-3 and BSL-4)
Healthcare isolation rooms and hospital HVAC systems
Chemical processing plants
Semiconductor fabrication facilities
A typical BIBO unit consists of a containment housing, a flexible changeout bag system, and secure access doors or ports. During filter replacement, operators use glove ports or sleeves to manipulate the filter from outside the containment area, ensuring that no direct contact occurs with hazardous materials. The contaminated filter is sealed within the inner bag, which is then detached and secured for safe disposal, while a new filter is installed using the outer bag.
For organizations seeking a trusted provider, YOUTH offers a comprehensive portfolio of BIBO solutions tailored to diverse industry needs.
