Frequently Asked Questions

What should I look for in a radon detector?

The best radon detectors provide ongoing radon detection and give you an extremely accurate picture of the radon levels in your household. Your radon detector should have long- and short-term results displayed and be able to store these results for long-term analysis purposes. It should also be intuitive to use and easy to install.

Should I get a short-term or long-term radon detector kit?

Radon levels can fluctuate within a short period of time, making short-term detectors more unreliable than long-term sensors. Long-term detectors do tend to be more expensive, so if you’re shopping on a budget, a short-term detector is undoubtedly better than none at all.
