The flush-out or testing will not affect installation of furniture and furnishings, as this can happen during or after the flush-out or testing, however, prior to beginning flush-out or testing, the following work should be completed to ensure that no toxins are reintroduced into your project space:

• 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 EQc5: Indoor Chemical and Pollutant Source Control, these filters must be MERV 13 or higher.
