Active or Passive?
Active or Passive?

Active or Passive? That is the question.

Radon mitigation systems have two major divisions, passive systems and active systems. The difference is a fan.

Active systems are most often installed in existing homes. These include an exhaust fan that is specially designed to funnel radon outside of the home.

Passive systems are most often installed in new construction and consist of a vent pipe that allows gases to flow out of the house (pictured here). These can have a fan added if necessary in the future, turning them into active systems.

The type you need and the way it is installed are determined by the unique circumstances in each home. The key is to get a professional mitigator to make sure the system that is installed is effective. Active or Passive becomes irrelevant if installed improperly.
