Radon Detection & Reduction

"Installed radon mitigation system in basement. Pros: 1) reduced overall radon levels by about 75% 2) they did the work in extreme cold temps 3) done in about 4 hours Cons: 1) They arrived late (although they did call to let me know) 2) they did not wear boot covers or put down any floor protector when walking on my carpet 3) they set dirty toolboxes and caulk guns directly on carpet 4) exhaust pipe is too close to roof peak and can be seen from street view of house Overall, good job. I can live with seeing the pipe from the street. I would recommend based on the overall work."

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.

You should have a professional test for radon every two to five years. A good rule of thumb is to get testing done every five years if you’ve never had an issue before and every two years if you have. You may also want to schedule testing if you notice symptoms of radon exposure or if you do intermittent DIY radon testing and notice changes in your levels between tests. If you have an active radon monitor, you can schedule testing if you notice levels increasing over time.

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.

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.
