Radon Detection and Reduction questions, answered by experts

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

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.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

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

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.
