Charcoal test kits

Overview & Pros and Cons

Overview:
Radon charcoal test kits are short-term devices used to measure radon levels in homes and buildings. They contain activated charcoal, which absorbs radon gas over a set period (typically 2–7 days). After exposure, the kit is sealed and sent to a laboratory for analysis.

Pros:

  • Affordable – One of the most cost-effective radon testing options. We offer a set amount each month for FREE!

  • Easy to Use – Simple setup; just place it in the home and follow the instructions.

  • Short Testing Period – Provides quick results compared to long-term tests.

Cons:

  • Short-Term Accuracy – Only provides a snapshot of radon levels, which can fluctuate daily.

  • No Real-Time Results – Requires mailing the kit to a lab, leading to delayed results.

  • Placement Sensitivity – Results can be affected by improper placement, drafts, humidity, or open windows.

  • Single Use – Cannot be reused; a new kit is needed for each test.

For a more comprehensive assessment, long-term radon tests (lasting 90+ days) or continuous radon monitors may be better options.
