Radon Detection and Reduction questions, answered by experts

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

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

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
