SAF Aranet Radon Detector for Home: 10-Min Measurement, Temperature, Relative Humidity, Pressure, E-Ink Display, 7-Year Battery, Portable with Free App, Bq/m3 & pCi/L Selectable

I've had this Aranet radon detector for two months; in that time it has functioned with no fuss. Tracks exposure levels for a seven day period (with the app).Pros:++Matched results from mail in laboratory test++Easy to set up++Intuitive and easy to read display+Aranet app easy to use on my Android device+Bluetooth connectivity has been greatCons:-More expensive than the competition-Bluetooth is short range (this doesn't bother me, just be aware this is not a WiFi device)Overall, I'm happy I went with this device over the alternatives (despite the cost) especially as this company seems to have a better reputation for accuracy than many of their peers.

Neat Radon measurement device. It operates with two AAA batteries. The front LED display provides the current Radon level, the ambient temperature and relative humidity. There is a battery level indicator and a 3-segment radon level bar graph. It comes with an illustrated user guide. It has bluetooth connectivity and apps for remote readouts to smartphones, as long as you are within the theoretical 33 foot bluetooth range. It had fairly quick response to changing Radon levels. I have it sitting on the top of a bookcase about 4 feet below a forced air return vent. I can see the reading change when the furnace comes on first thing in the morning after being off overnight. The Radon level in the basement runs about 1.6 and any where from 0.6 to 1.6 on the main level.

The radon detection appears to work well. Of course, there isn't much I can do to evaluate the actual accuracy. The temperature display also works correctly. The humidity display, instead, doesn't work: it always shows value around 30% humidity. I have an old, cheap non-electronic humidity detector, and it works much better than that. But I didn't buy the Aranet detector for the temperature and humidity (I didn't even realize they were included), so I still give this product 5 stars.

We’ve been concerned about the potential for high levels of radon in our basement. One of our neighbors told us his radon levels were reading well over 4.0 so he had to install an exhaust system. That led me to buy a test kit and send it in.I wanted something for continuous monitoring so I bought this. Not only is it very accurate, it’s wonderful to be able to track the history in the mobile app! Plus, the e-Ink display is genius. It’s very easy to read and requires very little battery power. I haven’t changed the batteries at all since I first set it up a few months ago. HIGHLY RECOMMENDED!One thing I learned is that the radon levels can be substantially higher than normal after rain or when the ground freezes. Radon is a gas and tries to find its way out. If the ground is wet or hard (or both), it has no where to go.Normal level in my basement is roughly 1.5 though this graph shows a bit higher - we’ve had a LOT of rain recently.

I have a radon mitigation system in my house that was installed before I moved in. Initially, I didn’t fully understand its purpose or necessity. To learn more, I purchased this device to monitor radon levels, and it has been working great. I’ve integrated it with Home Assistant to track radon levels and receive notifications if they reach a high threshold. However, similar functionality could likely be achieved using the device’s app.The device connects via Bluetooth, and since I keep it in the basement, I initially experienced occasional communication failures. To resolve this, I set up Bluetooth proxies throughout my house, which eliminated connectivity issues. It would be nice if this device could connect to wifi and not just bluetooth.I plan to experiment by temporarily turning off the mitigation system to observe how radon levels fluctuate and determine if the mitigation system needs to operate 24/7.

Great for peace of mind and to monitor for fluctuations. Has an easy app that lets you see trends over time. Love it! Seems pretty accurate based on results from professional test as well.

I love this Radon monitor. Big plus that my iPhone 16 and iPhone 10 work well with this monitor. My biggest concern was a negative review that his iPhone would not work and that maybe it needed an update. Everything graphs out on my phone. I also have their radiation monitor. My Radiation monitor usually does not fluctuate that much. The radon monitor response very quickly to different radon levels. It reads 2.48 pCi/L now. If. open my back door, it will drop to .7 or less in a hour.

I sent off a pair of side-by-side charcoal tests, and both tests showed the radon level in my basement was right around 10 pCi/L. I had also bought one of the Airthings radon detectors on a Lightning Deal, but this only registered ~4 pCi/L after a couple of days in exactly the same spot. I know radon levels can fluctuate wildly, but there was at least a day of overlap. Luckily, I was still within the return window of the Airthings device, so I returned it and bought the Aranet detector. After 24 hours, the Aranet device was giving consistent readings with the charcoal tests. I hired a radon contractor to install an active mitigation system, and he set up his own detector temporarily; at the end of two weeks the two devices had almost identical readings.There is an app for this device, but I haven't used it. It's easy enough just to look at the device every couple of days, and my readings are now consistently low enough that I don't feel a great need to look at the history.The Aranet device is more expensive than some of the others available on Amazon, and but my confidence level is much higher that it is accurate. This is easy to use, seems very accurate, and gives us peace of mind that the air in our home is safe.
