The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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

Installation typically takes 1-2 days, depending on the system and property layout.
