The following work must be completed prior to flush-out or testing to ensure that the air quality isn't compromised afterward.

• All interior finishes must be installed.
• All punch-list items must be complete. 
• All cleaning must be finalized.
• Final testing and balancing of HVAC systems must be complete. Other commissioning tasks can occur during flush-out or testing only if they do not introduce any additional contaminants into the building.
• Temporary filters and duct coverings used as part of the construction IAQ management plan must be removed.
• Filters must be replaced with new filtration media, unless the system is configured to filter only outside air. If your project is pursuing IEQc5: Indoor Chemical and Pollutant Source Control, these filters must be MERV 13 or higher.
• For BD&C projects, it is optional to install furniture and furnishings prior to testing or flush-out. For ID&C projects, movable furnishings must be installed prior to testing or flush-out.
