Airthings 2930 Wave Plus - Radon & Air Quality Monitor, Battery Powered (CO2, VOC, Humidity, Temp, Pressure)

First of all radon is no joke. I learned about radon many years ago when I moved to a state/county that is classified as EPA's Zone 1 for radon risk. I knew nothing about radon back then however the city/county did a fairly good job educating people about the dangers of this gas. One day I saw this big "Got Radon?" sign by the side of the road with a website to learn more about it. I was curious and followed through. What I learned was very concerning and questioned why I knew about the "dangers" of "mold" and not about a RADIOACTIVE gas that was lingering around my house. I think the answer is that we are obsessed with things that have short term impact but tend to bury our heads under the sand when we need to look ahead in the future 5, 10 or more years. We simply like to think the problem is not there because it is difficult for our brains to register the danger without immediate threat (like a scratchy throat). To cut the story short, I bought a radon test kit and the results came back at 10 PCi/L. We immediately took action and installed a radon mitigation system. Learning that radon levels can fluctuate I always dreamed of having a device that could constantly measure the levels of radon inside our house. Therefore I was thrilled when I found the Wave while browsing for IAQ monitors. We have own the device for a couple of months now, so sharing our thoughts: 1) This is a CONSUMER GRADE device, therefore users expectations should be accordingly. The value of owning this device is not to have a measure comparable to professional grade equipment but to have a close idea if you have a radon issue (consistent measures above the recommended threshold taken over a long period of time) or if your home is ok (consistent measures below the recommended threshold taken over a long period of time). This device will show you just that. In terms of accuracy of radon measurements, although we have only been measuring for a few weeks, we now live in an EPA Zone 3 county and we have seen Wave levels consistently measuring below recommended threshold. 2) This device measures CO2 (carbon "dioxide") not CO (carbon monoxide). I read some reviews about people's CO alarm not sounding when the Wave was registering high levels of CO2. Well, these are 2 different things. 3) In terms of temperature and humidity, we own several monitors in our home. Wave's measurements are comparable to these devices. I would say the wave is consistently 1 or 2 degrees above the cheaper "accurate" devices we have in the house. Same for humidity % 4) VOCs measurements are very impressive. We can immediately see the changes in results even with subtle things like sweeping the floors or bringing a box inside our home with things that had been in storage. We just bought a few Wave Minis to place them in the bedrooms as well. This monitor has helped confirm that passive and active ventilation are key to keep VOCs levels below recommended thresholds! 5) The app works well and is pretty user friendly. We had no issues downloading or using the app in our phones or iPad. Also, no issues registering the device. I think the level of information is what we need and it is great to have access to historic data. 6) Finally, this device requires CALIBRATION. The instructions clearly state that you need to place the device in its intended environment for 7 days to allow for proper calibration. We did exactly that and it seems to be working just fine. Overall highly recommended if you want a comprehensive view of the quality of the air you are breathing inside your home. I am hoping 5 years from now Indoor Air Quality equipment will be required, as smoke detectors are today.

I was originally looking just for a smart radon tester before I installed a radon mitigation system and found the airthings wave system. at first I purchased the home kit which comes with a older wave 2nd gen, the hub and mini wave from Amazon warehouse (openbox). I had some issues with the hub as it was already registered and didn't want to mess with support who wasn't available 24/7 and ended up returning everything . during the initial setup I also (wrongly assumed) that the units would be WiFi/Ip based but the stand alone sensors only work via bluetooth or via radio with the hub. also without the hub the data isn't constantly recorded . I then ordered this new sensor wave plus, 2 mini waves and the hub (quite costly). setup was a breeze, unbox the sensors, download the app, register for an account, connect the sensor via bluetooth to your phone , update firmware and it's readym Then you plug in your hub add to the sensors to the hub via your phone. With the wave2 the radon level was high (as suspected as ally neighbors got their radon level tested professionally for 150 bucks . What I didn't expect was the co2 and VOC levels to be high in the house as well as high humidity levels in the basement. the co2 we were able to lower by opening windows and airing out the house, and humidity levels controlled with a dehumidifier in the basement. As far as the VOC i started looking into UV lights in the hvac and ultimately ended up with a Airscrubber by aerus installed from my hvac guy. after the airscrubber and hvac fans running the airthings wave sensor picked up the improvements. the web dashboard also is has a lot better data and is easier to see track historical data than the app as the app will show you real time stats we well as historical but can't zoom in on the data or set a custom time frame (zoom in). also the wave mini has mold detection but the wave plus does not and the wave plus (primarily for radon) has co2 detection but the mini does not so would like a unified sensor even if it cost more as well as the ability to have wifi (although this will prob drain the battery) I'd also like an option of hardwiring the sensor similar to a smoke detector and alert/push notifications for user or presets thresholds so I don't have to constantly monitor. overall great product but will make you think about how to improve the air quality after seeing the data :)

Bought this unit to test overall air quality and realized we had a radon problem. Wasn't even looking for that, so I am grateful it was included. Here's the problem though... while it IS somewhat in the ballpark for the radon level, we discovered it erred on the low side after testing it alongside 3 other detectors - 2 similar type monitors of a different brand and 1 traditional charcoal test that we sent to a lab. Local radon mitigation companies trust the charcoal tests, they don't trust these monitors and told us to make sure we did the charcoal test too. Glad we did. Here's the thing... radon is a fluctuating number. After copious amounts of radon research along with my test results, I learned quite a bit. This monitor tells you that you must let it "calibrate" for 7 days to get a reading that is somewhat accurate and that 30 days is best. You really end up evaluating an average when understanding where your radon level is, but it doesn't feel good to see high spikes that get averaged out with lower ones. I like seeing where the top numbers land and how often. The app and information given is really nice and well delivered. In the first 7 days, our numbers for all metrics would wildly fluctuate. This particular monitor is not measuring with a high number of data points. I learned that quick and accurate radon testing requires a lot of data points. There are other monitors out there that do this much better because they have more data points (we tested alongside RadonEye that matched our charcoal test sent to a lab). The Airthings average level was lower by over 1 full point (the monitor was right beside the charcoal test). In radon terms, that too much difference (1 point is significant) to be considered an accurate monitor for me. But it WAS consistent after that first 7 days with its own measurements, going up and down consistently (higher at night, higher when it rains - all things you learn about radon when researching that proved true for us). But those averages were still lower than the other tests that also had consistency and, most importantly, matched each other. Airthings was the odd man out with the lower reading. And it takes this monitor a while to adjust to change (about 24 hours at least) while the other monitors give you accurate readings much more quickly (within a couple of hours) if you move it to a different room. Radon aside, I feel like the other metrics of VOCs, CO2, etc are probably pretty good. I didn't test those against another machine so I can't say for sure. But they did respond to change like fresh air coming in to the room, etc. Those metrics change more in real time which is nice to see. Overall, I love the look of the monitor, it's easy to place with not needing to be plugged in, the app is very easy to use and delivers the information beautifully. It only lacks in accuracy for radon in my experience. If that got better, I would choose this monitor over the others hands down. They are the same price for only radon testing and they need to be plugged in. I will be returning this one because I want radon accuracy but if I wanted the other metrics, I'd get this one without hesitation.

This device is amazing. I love, love, love it. We live in a neighborhood where a lot of people have radon reduction systems. Before we jumped on buying one of those, we got two of these -- one for the basement, and one for upstairs. While our radon has so far been low, these do alert us to other things, like high CO2, and are a great reminder to open up the windows and let the house breathe a little. I was a little nervous that you just wave your hand in front of it and get a color (green for good, yellow for OK, red for bad) without any other details, but the app is fantastic and provides all the detail you could ever want. Another super handy thing, they provide a very nice magnetic mounting plate, so we were able to put the one upstairs right under our thermostat, and it looks very tidy. If you're on the fence about whether or not it's worth it to monitor your indoor air quality, I would highly recommend trying this device. It's easy to install, easy to use, and seems very accurate (for example, the humidity reading is always in line with what our furnace and thermostat say, the temperature is always in line with what the thermostat says, etc.). In case you couldn't tell already, I really, really like this thing -- way more useful and handier than I could ever have expected. Now that we have these, I would never go without them again.

Not a professional, just a concerned father who wants to have his kids breathe safe air. - Pros: Looks nice - Cons: - Inaccurate testing less than 7-days for everything except temp - You have to buy a separate Airthings hub $70.00+ to use the app away from the house - Levels could read higher than they actually are which could cause needless concern - Different phones connected to Wave Plus app will display different results/numbers at same time To say I am disappointed in Airthings products would be vast understatement. The devices I used are fool’s gold with a dash of scam. After I purchased Airthings Wave Plus device, I read the instructions, activated it, and started my first test in my upstairs bedroom. Very quickly numbers were generated and radon and CO2 levels were in the red. With a newborn and toddler, I needed to correct this. I vented the room and grabbed 1 CO2 detector and then eventually a 2nd in case a detector was defective. Despite the high co2 levels, the detectors never activated. After venting the room, the numbers did eventually fall. I left the Wave Plus alone for a few days. The app showed that the radon and co2 levels remained unsafe at times. The high radon levels in my upstairs bedroom did seem odd, but I read that radon can actually travel to the top of homes through the HVAC systems. To verify the high levels, I ordered an Airthings Corentium (dedicated radon scanner) and 3 radon lab charcoal kits to verify the numbers. Radon does fluctuate, but my last long term (6 months) test in the basement was 2.2 pCi/L. To see how accurate this thing was, for the next 48 hours, I set up a table in my bedroom with the Airthings Wave Plus, Corentium, Charcoal kit, Ecobee 4 sensor, and Thermpro to compare numbers. I also set up 1 lab kit in the basement to see what the numbers were and if radon could be moving upstairs through my hvac system. Once the first 48-72 hour test was completed, I moved all the testers to the basement (minus the ecobee sensor) and started another 48-72 hour test setup. *Results data uploaded to review*I was up every 2-3 hours to help feed newborn and would check results after --------------------------- Test 1 (bedroom) Radon Averages: Wave Plus: 3.21 pCi/L, Corentium: 2.07, Charcoal Kit: 2.6 pCi/L basement Charcoal kit: 3.8 pCi/L – Temp averages: Wave Plus 76.3, Thermpro 74.7, Ecobee 4: 74.4 Humidity average: Wave Plus 37%, Thermpro 33%, Ecobee 4 39% --------------------------- Test 2 (basement) Radon Averages: Wave Plus: 5.04 pCi/L, Corentium: 3.82, Charcoal Kit: 3 pCi/L – Temp averages: Wave Plus 68, Thermpro 67.9 Humidity average: Wave Plus 38%, Thermpro 32% --------------------------- The short term results (48-72 hrs) for both Airthings products are ridiculously inaccurate. The best thing I can say about these products is they might give you a glimpse at your radon level. Wave Plus looks to read high .5-1.5 pCi/L and Corentium looks to read about .5 lower than a during the same time. The Wave Plus appears to only be accurate for temps. I did buy an air purifier that monitors air quality and does a simple color display, Blue (good), yellow (average), red (bad). When the purifier was blue, the Wave Plus would be red, etc. Considering how inaccurate the radon results are, I trust the purifier. for testing less than 7-days, these products are a disaster. It is possible it does better long term, but I will not make it that far before returning. You also need to buy their very expensive Airthings hub to use their app away from your house. **Update** 10/16/20I connected two separate phones to the app at the same time, a Pixel and an I-phone. The app displayed different readings for the same device at the same time. How? Is this product even legit? Has anyone else experienced this?

I wish I'd bought this a year ago. I'm doing progressive radon mitigation on my home. When I discovered the problem about 14 months ago, I first bought the Airthings 223, which gives accurate daily, weekly, and long term readings on its built in display. It was really useful, but I recently added this one, the Airthings 2911, and it has changed everything. I'm now able to track the ebb and flow across the hours of the day, week, month, year. Readings shown in hour intervals allow you to make sense of daily patterns and changes, for example, weather changes, family coming and going, thermostat settings, day/night, etc. Also exceptionally useful is having the data automatically laid out in graphs, to track against larger patterns like season change, cold fronts, and ongoing mitigation steps. Yes, you have to use the phone app or web interface, but both are easy (with fine-grained data on the web interface, much more so than on the 223). Also helpful, but secondary, are the other measurements. VOCs are nice to see (watching the profound effect of different uses of the gas stove, eg.), and the CO2 graphs are entertaining but not a real concern in my old, gas permeable home. Temp, pressure, etc., are mainly useful as a handy comparison as you're trying to make sense of radon changes. Purely in terms of expense, this has already saved me more than its cost by giving me the ability to pinpoint the interventions that count. Its accuracy matches fairly well the readings on the 223 unit, which in turn has matched other (charcoal sent to lab) tests I've run. Finally, if you like hard, detailed data, as I do, you can DL a CSV file with what appears to be raw readings EVERY FIVE MINUTES since the day you turned the sensor on! Takes a little auto-replace work to make the file cleanly readable in Excel, but, still, wow.

We have three fan/purifiers already, but they do not report Radon or CO2. However, they do report HCHO, and NO2. Now our air quality coverage is through. I’m not concerned with Radon in my home, but I am concerned about CO2. My first purchase was a View Plus and Wave Enhanced. I was reluctant to purchase because on the web I didn’t see good descriptions of the products; what they reported, and how they worked together, especially the Hub function. There is information and user guides on the web, but they are not .pdf or downloadable. The product comes with the typical start-up guide, but that’s pretty much it. So, the consumer must self-inform concerning product, set-up, and how best to use it. The premise is that the customer is already informed about air quality and tech advantages. I struggled through understanding the “Hub” benefits and function. The Hub costs more so it would be nice to know all the benefits. I consider myself about 6 on a on a tech savvy scale but struggled with setting up the Hub and connectivity at first. Clear, precise instructions, and downloadable owner manuals would have been helpful Once set-up I am thoroughly satisfied with Airthings. Now I monitor air quality and take appropriate action like opening windows to mitigate high CO2, VOC and PM levels. After the first set-up I did have a connectivity problem and followed all the web-based troubleshooting directions. Finally, I sent an email, as chat takes forever and is time consuming. The email function says they have up to 24 hours to respond. Within an hour Don contacted me by email and after two or three exchanges he elevated it up to their tech service department. In the course of that time the issue was resolved. The next day it occurred again and was resolved by the IT department within hours. Don was appreciative of the follow-up report and Airthings accepted responsibility for the digital problem. For me, it was the initial set-up and troubleshooting that was tiresome. Once resolved everything was nominal. After my first experience and the excellent customer service from Don I decided to purchase the Wave Plus for total home coverage. That set-up was seamless, easy peasy. I’m highly satisfied with the residential Airthings product line. Yes, they are pricey; but their customer support is in parallel, their product quality is unsurpassed. Although not made in the USA they are a quality European product, and I would rather support Europe than China. Last comment. Wait until they are on sale and then jump om it.

I bought this device primarily for two reasons: sale price vs quality of the consumer-level sensors and the fact that it is Bluetooth-based. I believe that any information this device collects is for me, the homeowner, and nobody else. This is where I was wrong. The device relies on the mobile app for its management and data collection. This app downloads the information from the device (and you do not know what else) and uploads it to Airthings cloud. And then pulls the information from Airthings to display it to you. This is not what I expected. I am not OK sharing any information about the device or the environment, no matter what it is, even CO2 level at my home. However, I found a way to use this device without any dependency on the external services - there is a nice add-on for Homeassistant (free open-source smart home app) capable of reading the data from this device over Bluetooth. And this add-on works perfectly and it is super easy to install, if you use this app already. So, technically, you do not need the dependency on Airthings except for the software updates. At the same time, I have found that this device has ZERO security. It allows anyone to pull the data from it over Bluetooth without any restrictions (like the need to pair) etc. So, I would assume, anyone can actually connect to this device - there is no button to press to confirm etc. This is the worst example of an IoT device I have ever seen. You are at the mercy of your neighbors - if you have people living in dozens of meters from you who know something about computes and have too much free time, they can break into your device without you even knowing. This is the only reason why I consider returning this device now. As for the sensor quality, they appear to be OK. I used other devices in my home before to measure CO2, I did a traditional (slow) radon test before - I think what I see is consistent. Again, I look at it as a consumer device, not a pro tool.
