• Draw in outside air (with fewer pollutants)

• Distribute outside air throughout the house

• Prevent growth of mold and mildew on walls and in insulation.

To ensure healthy indoor it is ideal if the home has been built using nontoxic materials (low or nor VOC) , nonpolluting appliances, furniture and furnishings that are free of toxic compounds, and any potential toxicants have been blocked off or guarded against.
