DIY Radon Testing

Everyone should test their home for radon, and it's very easy to do it yourself. There are basically two options, either a low cost single use device, or a prosumer electronic device. Here are my top recommendations for reliable test devices that you can purchase online. These are affiliate links and we receive a very small commission if you purchase which helps to support our research. Thank you.

The first option is a low cost single use charcoal type test kit, a great option for doing a quick screening test and follow-up tests. If you've never tested for radon, or it's been a few years since you last tested, this would be the best first step. Here are two kits I can highly recommend.

Airchek Radon Test Kit

Airchek Labs Radon Test Kit

Airchek has been around for decades and is a stellar laboratory. These test kits are trusted by the radon measurement industry for commercial building testing, I use them myself. Very easy to use and quick results from the lab.

The second option is an electronic continuous monitor. For about the same price as a professionally assisted radon test, you can purchase your own real time radon monitor and check your radon level whenever you want, right on your smart phone! Something you might consider if you have a radon mitigation system in your home and want to make sure it's working correctly at all times.

Radon Eye

Radon Eye RD200 Real Time Radon Monitor

The RD200 tracks the radon level in real time and stores readings every 10 minutes. You can download the free app to your smart phone and this lets you check the radon level directly on your phone over a bluetooth connection. There is also a digital readout on the top panel. In the app, you can set an alarm warning level. When the radon level exceeds that level it beeps at you. You can get a 5% discount by using the link below.

Airthings Wave

Airthings Wave Real Time Radon Monitor w/Temperature and Humidity Sensor

The Airthings Wave is similar to the Radon Eye monitor, except it also monitors temperature and humidity levels. The reason they call it the wave is because it has a cool feature where you simply wave your hand close to it and a colored ring displays. If it's green, the level is OK, of it's orange the level is approaching the action level of 4 pCi/L. Red means it's above the action level of 4 pCi/L. So you don't even need your smart phone to get a reading.
