Mankato, MN Radon Fans
Radon is a radioactive gas that cannot be detected by human senses.

It is present throughout the United States but is more prevalent in certain areas. Radon damages lung cells and is believed by scientists and environmental authorities to be the second-leading cause of lung cancer in the United States. There are several ways of dealing with radon gas inside of a home. Homeowners often install systems in their homes that use Mankato, Minnesota radon fans to exhaust the gas from their homes.
Radon fans in Mankato MN work by drawing radon from the soil underneath homes and then venting the gas through pipes and harmlessly into the atmosphere. Radon naturally occurs at very low levels in the atmosphere. The design of systems using radon fans in Mankato Minnesota is not complicated but choosing the correct Mankato, MN radon fans requires understanding the requirements for proper operation.
