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.

Avoid opening windows and keep doors closed during testing to obtain accurate readings.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.
