## What's a Bag-In/Bag-Out Filter?

Service-Tech technicians are equipped and trained to perform a specialized service known as Bag-In/Bag-Out filter changes for facilities with containment housing systems designed to trap harmful materials. Bags are used to seal the housing while filters from the isolation structure are replaced so that no contaminants can escape into the ductwork, polluting the building and placing occupants at risk.

 

## Who Needs a Bag-in/Bag-Out HVAC Filter?

A number of different facilities call us to service this type of secured filter system, including hospitals, pharmaceutical labs, biotech and bio-safety facilities, veterinary offices and animal shelters, and industrial plants dealing with toxic materials.
