Since starting BreatheSafeAir, I’ve often been asked if I plan to review radon monitors. Until now, I haven’t dipped my toes in the field of radon monitoring, and it’s been interesting to me for a while.
After receiving a few monitors around a month ago, I wanted to announce that I am now working on a range of radon monitor reviews, which I will share here once they are complete.
I’m first working on a review for the Aranet Radon Plus, followed by the RadonEye, EcoCube, and Airthings Corentium. While I’m not quite sure of the exact order in which I will review these devices yet, all four reviews should be completed within a few months (as I am also working on some other articles alongside these).
I also have the Airthings View Plus, which features a radon sensor. However, I’ve already completed a full review of that monitor from the point of view of someone looking for a comprehensive air quality monitor. I am, therefore, looking forward to trying this range of dedicated monitors.
Please let me know if there are any other radon monitors you would like to see me review! I would love to try more of these monitors and am open to suggestions. I’d also love to hear your thoughts if you’ve tried any of the monitors above.
It would be nice if you could also review the Air-Q Radon, which seems to be the only device which is capable of measuring Radon every 2 minutes. As this is a new device, there is currently no comprehensive comparison available.
You can get the 5 sensor version from here:
I have been looking into consumer grade radon monitors as radon is prevalent in my area. I have had radon mitigation done years ago, but I would like to monitor for effectiveness and to see if alterations in my home trigger issues. Radon seems like it’s a difficult thing to monitor and there is a range of quality issues on the consumer side.
From what I have seen so far, the EcoSense EcoQube and RadonEye seem to be well regarded. Unfortunately, the EcoQube doesn’t integrate into Home Assistant (which I will be setting up). The RadonEye appears to have some work arounds to get it to pair, but some of the newer models may have difficulty.
The Air-Q products look pretty nice and I like that they have multiple sensors which could help correlate the conditions which cause Radon spikes so that you could remedy. They come with a heavy price tag unfortunately.
It’s funny that you mention this! I’m actually working on getting an Air-Q monitor for testing at the moment. While it will take a while to get here (and a while to test the device), I will hopefully have a full review to share in the next couple of months.
I’m quite curious to test these monitors, especially the comprehensive variants, as they could be a great (albeit very expensive) option for anyone looking for a high-quality all-in-one monitor.
Also, I could be wrong, but I believe the Aranet Radon monitor has quite frequent updates. Of course, the longer-term readings are typically much more accurate and should be relied on much more than the shorter-term readings.
Where are you based? I only ask because, while I have both the EcoQube and the RadonEye, I haven’t yet been able to fully use them because the apps for both appear to only be available in a few countries (the U.S. and I’m sure a few other larger markets). Therefore, I would not recommend either of these devices (especially the EcoQube, which seems completely unusable without the app) unless you are in the U.S.
With that said, if you want something that integrates with Home Assistant, the Aranet Radon monitor is also worth looking at. While it doesn’t yet have third-party testing as it’s very new (I’ve been told they’re working on this at the moment) it has the best integration out of the monitors I’ve tried.
I am located in the US, so the app would work in my situation. You’re correct that the EcoQube would have no functionality without the app. The Radoneye would be limited as well I believe. I believe they have been promising an API for years, but it has yet to materialize.
Thanks for pointing out the Aranet Radon Monitor. I had originally dismissed it due to its newness and partially cost. However, it does look promising. I like that it includes some additional atmospheric measures to potentially help understand radon fluctuation. Fantastic that it has Home Assistant integration as well.
That’s good to hear; in that case, you have a lot of choices! Yes, the RadonEye will work without the app (the screen still shows the concentration), but other than that, it will lose all of its functionality.
I can understand your stance on the Aranet, and if you want to wait for third-party testing, that’s very understandable. That said, Aranet has a good track record, and its other devices are well-regarded, which is the only reason I think this is likely still a good device before we see some third-party lab/testing results. Its feature set (like the HA integration) also makes it very appealing, and it has, by far, the best app of the monitors I’ve tried.
I’ve found all Aranet devices connect quite well (to my Raspberry Pi) as long as they’re within a room or two. Anything further than this, and I guess something will be needed to extend the range.
However, as long as they’re within range, I’ve found that they stay connected with very few dropouts.
