Airthings Radon Detector

The Airthings Radon Detector is invaluable for homeowners. It reads radon levels so you're aware and can take action if the levels are high. I have a radon mitigation system, so my levels are usually below 1, but I still want to immediately know if they ever go higher. The Airthings Radon Detector gives me peace of mind.

Works well. Would buy again.

Price was very fair and it quickly arrived in perfect working order. Worked as it should have right out of the box. Batteries included was a nice plus. Readings are accurate as far as I know. I had the same one which konked out after six years. This one is an exact replacement.

Monitor radon in your home with this simple device

This seems to be a very accurate, easy to use radon detector. We had elevated radon in our home and wanted to see how bad it was. It was an inexpensive way to get a continuous monitor. We did end up needing to mitigate and it is still keeping us informed of our now very low levels. We gave it to all of our kids to test their homes and apartments as well. Radon is serious business, we recommend everyone test.
