"Black Dog clearly explained the radon problem in the house and the proposed mitigation plan. He was professional, knowledgeable, and a pleasure to deal with. We explained to Eino Anttila our concerns about having the high radon levels while our infant grandchild would be visiting from out of state and he went above and beyond to install the mitigation system before they arrived. He was able to reduce the high radon level to an acceptable level. He even monitored the mitigation system in our house while he was on vacation out of state and sent us reports. We highly recommend Black Dog Inspections."

Radon Detection and Reduction questions, answered by experts

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.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

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.

No level of radon is technically safe, but because it’s everywhere—even in the air outside—it’s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.
