Bag-In/Bag-Out filtration keeps contaminants contained during filter changes. This guide explains what BIBO is, where it’s used, and why many facilities now outsource changeouts and disposal for safety and cost control. Go to https://www.pfpspokane.com for more information.
Bag-In/Bag-Out (BIBO) is a containment method that lets technicians remove and replace filters without exposing people or the room to captured contaminants. The housing is fitted with a flexible sleeve and clamping system, so the used filter can be sealed before it leaves the airstream, and the replacement can then be installed.
"A typical BIBO housing holds HEPA or ULPA filters, sometimes alongside carbon or specialty media," explains Spokane-based Pure Filtration Products. "During changeout, the outer bag is attached to a perimeter ring, clamps are moved in sequence, and the used filter is enclosed before being removed. The process keeps captured material sealed so the air handler and surrounding environment aren’t contaminated."
You’ll find BIBO in spaces that can’t risk escape of particles or fumes, such as hospital isolation rooms, pharma and biotech labs, microelectronics cleanrooms, and some chemical and energy facilities. Adopting bag-in/bag-out filtration systems is about maintaining performance while protecting staff during routine maintenance.
Bag-In/Bag-Out filter systems are being added in more facilities as rules on containment and worker safety tighten, and audits are expected to show clear, written steps. Teams need proof that hazards stay sealed during filter changes, with records to show it. Recent air-quality events and stronger infection control have also made cleanroom upgrades a senior management priority.
Because the filter is sealed inside a bag and waste stream, changeouts involve more PPE, sequencing, and paperwork than a standard swap. Teams typically perform a job hazard analysis, isolate airflow, verify pressure, and complete a post-changeout check. That added control is the point of BIBO: safety and consistency during an otherwise routine task.
BIBO programs depend on clear procedures and thorough records. Many facilities use standardized checklists for PPE, bag integrity checks, chain of custody, and post-changeout verification, such as airflow measurements and particle counts. Complete documentation simplifies audits and helps quality teams confirm that maintenance did not compromise the room or its classification.
Pure Filtration Products notes that many facilities now meet added BIBO requirements by outsourcing certified changeouts to specialist teams. External crews provide documented procedures, trained technicians, and compliant waste handling, reducing training load and audit exposure. Before selecting a partner, align housing design, filter specifications, waste classification, and record keeping, and look for providers offering certified BIBO filter changeout services to minimize disruption.
