Why do you need a Radon Fan?
Radon is a cancer-causing natural radioactive gas that you can’t see, smell or taste. In small doses it is not harmful. However, in today’s better insulated homes, Radon can accumulate and be a danger to your family’s health.

You need to test your home for Radon Levels. If/When you determine that you have dangerous levels of Radon in your home you will want to call a professional to help eliminate this problem. Make sure that you are getting a Fantech HP220 Radon Fan.
The Fantech HP220 is an excellent choice for systems with elevated radon levels, poor communication, multiple suction points and large subslab footprint.
