Control Soil Gases
In addition to radon, the soil around your home can contain different types of naturally formed and manmade gases. Contaminants like methane, hydrogen sulfide and other volatile organic compounds (VOCs) from manmade sources may also be present and can negatively impact home air. Also, mold occurs naturally in the soil and will produce VOCs in your home's air.
Most of the time these various elements are present in concentrations too low to detect or to threaten your home air quality and cause illness, but problems can arise with unpleasant and unhealthy effects. The runoff from common pesticides used in your neighborhood throughout the years, as well as some other naturally occurring VOCs can adversely affect your family's health.
An Active Soil Depressurization (ASD) System (with a radon fan as key component) installed by a certified professional can assist improve indoor air quality, removing most of these contaminants and VOCs before they have a chance to enter your home's air.
