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 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'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.

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.

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.

This is a wonderful product. I replaced another radon detector which also wasn't cheap but didn't provide real-time readings, just averages over either a day or a week. This one does that too, plus 30 days, plus gives you a live radon reading. I see the values change as I ventilate the house. Worth the high cost, IMHO.

Works great. Like how well it works on batteries, able to easily move around and map out problem areas.

This is a must if you are selling your house - you can provide potential buyers with hourly radon levels over the last months to prove your radon mitigation is working and save the time and expense of a one time test.
