Performing an air flush is a technique used to remove pollutants that were introduced indoors during construction prior to occupancy. An air flush is a process of supplying outdoor air to the building at a high rate for a certain period of time to dilute and flush out the indoor air pollutants3. An air flush can help reduce the levels of volatile organic compounds (VOCs), formaldehyde, dust, and other contaminants that may have accumulated during construction or renovation4. An air flush is required by Feature A03: Air Flush5 of the WELL v2 standard for projects that have undergone major renovations or new construction.
