Direct the inflow through a wall or from the outside.
If outdoor air pollution is the source of your poor indoor air quality, the InFlow W125 ducting kit teamed with your IQAir air purifier may be the solution. The InFlow W125 will allow your air purifier to draw air through a wall or from outside. In this setup, an IQAir system also serves as a ventilation system, bringing in oxygen-rich outdoor air while removing undesirable outdoor pollutants such as pollen, mold spores, dust and exhaust soot. As a result, fresh and filtered outside air comes into the room.
