Radon Relief
by Kate O'Brien
Improves air quality while it
mitigates radon. Current Indoor Air
System Model #300 is the product of
over 15 years of research by industrial
engineer Hoyt Mitchell. The system
uses concentric piping, outdoor wind,
and a low-power fan to produce a
positive pressure barrier in the
basement or ground floor of a radonimpacted
home. Pictured above are
the components: one rotating wind
scoop; two 5-foot sections of air-to-air
heat exchanger, one variable-speed
fan (Kanalflakt, 270 cfm); and one
6-inch pipe reducer. According to the
manufacturer, the system has been
successfully field-tested in several
houses where other radon-mitigation
techniques had failed. For more
