[This review was collected as part of a promotion.] The Airthings Corentium home detector is a great little home unit that provides peace of mind as well as actionable intelligence for conditions in your home. Not only does it give you up to date and aggregate data concerning Radon conditions; It also gives you humidity levels and temperature. The app is very straightforward and the unit itself is essentially foolproof. Setup is as simple as you could imagine. Its easy to move around, just place it and forget it. Well done Airthings.

[This review was collected as part of a promotion.] I live on the ground floor, and this device turned out to be essential for me. The portability is a huge plus — it’s lightweight and easy to move between rooms. The data analysis is clear and easy to understand, showing both short- and long-term radon levels. I’ve been using it for a few months now and it’s held up really well, so I’d say it’s quite durable. The battery life is impressive — I haven’t had to change them yet. Most importantly, the accuracy seems spot-on, as I’ve noticed consistent readings when moved back to the same location.

[This review was collected as part of a promotion.] This is a reliable device and easy to use. It provides a peace of mind. It took a little over 12 hrs before it started reading so take your time. I do believe it’s an expensive product to buy. I would say that based on my amateur and interpretation of the results, that the device is probably reliable and accurate enough to get a decent approximation of the radon levels in your home.

Great new product

I have used Airthings radon and air quality monitors for a few years and credit their products with finding serious radon issues in not only the old house on property we bought to build a new home, but when we loaned out several of the monitors to neighbors and they had readings that ranged up to 325 they were able to cure problems they did not know that they had!! The old house on our property had a radon level of 16! In the new house we have passive radon systems and intend to turn the fans on when we move in, but have tested to see the results without them to be able to record the variations that can be seen, based upon weather, etc. The Airthings devices give us the confidence that the radon levels are well understood and managed and we will always be able to see our air quality levels. We have used View Plus units and Corentiums. I am a big fan of the Corentium Home 2 as it provides the reporting features that we are very pleased to see added to the Corentium.. I was a beta tester for this product and they sent me one to test. While not everyone is going to buy one to have in their home, indoor air quality has a great impact on the quality of life and knowing if you have air quality issues allows them to be addressed.

The monitoring chart and values are super helpful. An essential tool to monitor Radon levels in the basement, so I know exactly when it is time to open my windows. No Bluetooth sync issues whatsoever. Highly recommend!

Getting started with Corentiun Home 2 could not be easier. Getting the unit operating and connected to the Airthings app was a breeze. I have been using the product for a couple weeks to monitor my home and was pleased with the data it provided. The date provided put my mind at ease about my radon mitigation system. So far everything is in the good range. It's nice to know I can keep an eye on things moving forward. FYI I participated in the Beta Testing program and received the product in exchange for feedback.
