"Had them come out to install a Radon Mitigation Fan. Service was fast and the installer was extremely knowledgable. He was in an out within an hour and the radon dropped from a 4 to a 0.59! Extremely happy with the result. Price wasn't cheap by any means but definitely fixed our problem."

Radon Detection and Reduction questions, answered by experts

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.
