Airthings 2950 Wave Radon - Smart Radon Detector with Humidity & Temperature Sensor – Easy-to-Use – Accurate – No Lab Fees – Battery Operated - Free App

We recently had a radon mitigation system put in our home. We wanted to continuously check the radon levels so that we can make sure we are safe. So far it is working perfectly and was easy to setup. It is small enough that we just have it on a counter in the basement, it is giving us updates in an easy to read manner, and the readings it is pulling seem accurate to what our radon company saw. Quality is good for what this is. White plastic that will be durable in case of a fall, but nothing unnecessarily fancy. Should last a long time.

This Airthings Radon Detector is a great supplement to my DIY radon mitigation system. My biggest hesitancy before purchasing was whether or not it would be accurate. Several reviewers questioned whether it was accurately calibrated by testing it next to home test kits and inspector-rated machines. I had my home professionally tested twice prior to purchasing this device (one 48-hr test in summer and one 72-hr in winter). Although I did not perform a side-by-side comparison, the averages and ranges detected by this Airthings monitor have been within a close enough range to the professional tests to make me comfortable with it’s accuracy. Two separate radon professionals informed me radon levels change hourly depending on many factors including weather, air pressure, air movement in the home, temperature, and random emissions from the radioactive minerals underground. After 16 weeks of use with this Airthings monitor, I have noticed several trends, like spikes in activity when a large rainstorm brings runoff (presumably radioactive) water into the crawlspace, or when the house is left dormant for a weekend trip. After collecting a 13-week baseline, I installed a radon mitigation system and have noticed the Airthing’s monitor detect less radon hourly. I can watch the radon levels build up or drop by turning my radon mitigation fan on or off. This response along with comparison to my previous professional tests gives me confidence this device is accurate. I’m glad I purchased it.It was easy to install bafter downloading the app. The added humidity and temperature features are nice to have. And the bluetooth connection has a surprisingly long range. I can check the levels from my phone throughout multiple rooms and floors of my house.I would recommend this product to anyone who’s on the fence.

I've had a home office in the basement for years, but due to Covid found myself spending more time down there than ever. A month or two into lockdown I seemed to be having shortness of breath issues and thought for a while that my mind was just playing tricks on me, "do I have the sickness..."? Well, I let that go for a while and when it didn't get better I did some research and decided to check my radon levels.I started with a mail in 3 day charcoal kit which came back somewhere in the low 4 range, not great, not terrible either since 4 is the recommended max level. Finding out that radon can vary over time, I decided to buy the Airthings Radon sensor.Overall, setup was quick, I agree the bluetooth design is a little annoying, but I've never had an issue syncing as long as I was in the normal 30foot range that bluetooth has. It doesn't sync in the background, only when you open the app. A WiFi option would be nice, but that would require a power cord, and I did appreciate that I could move this device around to several locations in the house which was easy with it being on batteries.Accuracy: After the 48 hour "acclimation" period, I saw the reported radon levels come right into line with the lab report. Then it kept climbing, then it dropped to almost nothing back in the green range, then back to red. Over and over every 2-3 days I'd be green, red, green, red, and I started to wonder if it was just a gimmick to make it look like it was doing something. It did seem to change with weather, but I could never put my finger on a pattern as the weather is always changing. Then I moved it from the basement to the main level for a few months, and the average was slightly lower, but I still bounced between acceptable and unacceptable levels.Finally, somewhere in the process I got actual Covid, got over it, and felt pretty much the same as before but I started to notice I felt better when I wasn't at home. We traveled for Christmas and had a vacation or two since someone has to keep the economy going... So I finally decided to install a radon fan on the passive pipe which was installed on our house during construction as required by code these days. The Airthings device had no way of knowing I just installed a fan, but it clearly picked up on the environmental change. In the screenshot you can see the radon level fall off a cliff and flatline in the green. In short, I no longer question if it was actually measuring anything, this thing works!I was surprised by the variability in radon levels over time, and I'd recommend anyone who's concerned to get a sensor like this. Go ahead and get a lab test as well just to confirm the sensor is good any working, but I do think there's a delay between your radon level and when it shows up on the sensor. This is surely why they tell you to wait 48 hours after setup before looking at the reading. I tried many times to open a window in my office when it turned red and never saw a blast of fresh air to make a difference. I'm not a physistist, but the sensor probably takes time to absorb or react to the radon, so let it sit and watch the trending over time.It's only been a week since installing the fan, and maybe my brain is giving my lungs a placebo effect, but I feel like it's made a difference.

We've been using the Airthings 2950 in our home, and it has worked well for monitoring radon levels. The readings do fluctuate, so we're not entirely sure about the device's accuracy, but the levels were definitely high enough to warrant a mitigation system. After installation, we saw a sharp drop-off in the readings, which has been reassuring. Overall, this device has been a useful tool for understanding our home's radon levels.

I've been using it for over 2 years and very happy with the purchase. When I first ordered it, I had my doubts about it's accuracy and also ordered 2 mail order test kits. The test kits, which were activated at the same time reported 4.6 and 6.5 radon levels, and the Wave was reporting in the same range. It often reports higher radon levels during extended periods of rain. When a radon mitigation system was installed radon levels dropped from around 5 to below 2. A year later when the radon system lost power, it was the Wave device that alerted me that radon levels were back up to 5 and when the radon system was turned back on a few days later the Wave was reporting levels below 2. I'll probably be a customer for life. :-)
