Airthings 2960 View Plus - Battery Powered Radon & Air Quality Monitor (PM, CO2, VOC, Humidity, Temp, Pressure)

Tl:dr I recommend this product. I believe that it is currently the best on the market and provides a good array of sensors for the price. I have not received any financial or other consideration for this review. I have no connection to the company. Details, positive and negative, are found in the review. Intro: In operation (after 7-day calibration) for three weeks beginning October 2021. Unit is located indoors in the bedroom of a small single-story home in northern California. I purchased View Plus after an online evaluation of competitive units. The purchase decision was based on the array of sensors, acceptable display of sensor parameters, appearance of a good user interface, ability to easily download the data in Excel .csv file format, designed in Norway, and assembled in Tunisia (visible in product photos). I expect that this is the first product that I’ve ever owned that was assembled in Tunisia. There were no Amazon reviews as I purchased the unit as soon as it became available. My primary motivation for purchase was to measure indoor particulate pollution during the wildfires. I wanted a more quantitative measure than the colored indicators on our air purifiers. However, I have since become more interested in the carbon dioxide (CO2) and VOC levels. The inclusion of Radon, temperature, humidity, and atmospheric pressure sensors is a plus. Particulates: I have had an extended conversation with Airthings via the app. They are responsive, although it may take a few days or even a week, if you ask technical questions as these need to go to the engineering team. As this is a consumer and not scientific device, there are cost limits on the nature of the particle sensor. Airthings does calibrate the particulate sensor to a scientific instrument. However, the Airthings sensor is most likely not able to distinguish between different particle size and scattering distributions that give the same overall signal. I had plans to do a cross correlation study with a scientific instrument, but circumstances conspired against me. At this time, I am satisfied that Airthings has done enough work that the threshold limits (green <10, yellow <25, and red >25 µg/m3) for the PM 2.5 sensor are reasonably close to the equivalent limits used by the US EPA and European PM 2.5 AQI. For the data that I’ve collected, there is very little difference between PM 2.5 and PM 1 signals. I have not investigated why. One caveat is that the data collected so far has an average PM 2.5 and PM 1 values of only 2 µg/m3 and only a single peak greater than 25. Since the rains have (finally) come, I don’t expect to have the opportunity to check against more polluted air conditions in the near term. Carbon dioxide: This provided the most surprise about the conditions in our home. I found that ventilation in our bedroom is insufficient to keep levels in the green without the window(s) being open at night. I am looking into ways to ameliorate this problem when keeping the windows open is not an option. When I first received the unit, I placed it outdoors to see if it would read the expected value of about 400+ ppm for average CO2. The unit read about 550, but it was before the 7-day calibration was completed. Over the course of the past month, when the room was well ventilated, I observed readings as low as 469 ppm. The unit will show the increase in CO2 when either 1 or 2 people are in the unventilated room for any significant period of time. VOC (volatile organic compounds): The measurement is in parts per billion, ppb. This is my first experience with VOC data recording. The unit is certainly responsive and exhibits significant signal when we are cooking, especially frying. As there are many different types of VOC, I cannot comment on whether one should take significant actions based on the results in the home. Do fry-cooks have career related health issues? At a work environment, such as an organic chemistry lab, there may be many types of VOCs that are clearly harmful to health. Radon: All the values that I have recorded are below the green threshold limit of 2.7 pCi/L (picocuries per liter). The average value over 2000 measurements is 0.7 and has a standard deviation of ±0.4. Temperature: Comparing the value to household sensors indicates that the temperature displayed by the Airthings sensor maybe between 1- or 2-degrees F high. However, I consider that within measurement error for accuracy given the nature of the other sensors. Precision appears to be excellent. Relative Humidity: Comparison only with household sensors. Appears to be within a few percent. Atmospheric Pressure: Excellent agreement (within 0.5 mBar) with external values (local weather data). Range of data recorded between 1001 mBar and 1022.5 mBar. User Interface (Unit): There is an E-Ink type display that is not illuminated. This is a very low power display and conserves battery. No power used to maintain the current display reading. It has high contrast and easy readability. You can choose 2 sensors to display via the app (Phone or PC). When you wave your hand in front of the unit, it indicates its assessment of the overall air quality (good, fair, or poor) and shows any of the readings that cause a fair or poor result. It then returns to the standard readout. I have not found the lack of illumination to be detrimental. User Interface (Phone): I’m using a Samsung Galaxy A51 with Android 11. The software allows you to choose among several devices that you might have. As I have only one, it displays a summary that is in the attached photo. You can then tap “VIEW IN WEB DASHBOARD” to get graphic displays for different periods of time. You can choose to get notifications via the app, if values exceed the Airthings recommended thresholds. You can choose the sensors for which to have notifications sent. These thresholds cannot be changed. I think it would be good to be able to change the thresholds with the understanding that one is responsible for the values used. User Interface (PC/Web): I’m using an Intel-based PC running Windows 10 Pro and MS Edge for this unit. See attached photo. The graphing is generally quite good. I’d prefer to be able to choose the order in which the different sensors are displayed. It might be possible to do this by deleting sensor graphs (called tiles) and then adding them back. I’ve not tried that. The vertical scaling is automated and determined by the range of values of the data being displayed. The scale cannot be changed, but you can zoom using touch, if your computer/phone has that capability. Adding the historical data (not shown in the photo) will expand the vertical size of each graph and give the minimum and maximum value for the data range. Bug: You can add a tile for the outdoor weather, but only for Oslo, Norway! They have given me instructions for changing the location, but the software for the View Plus is not the same as for the software shown in the instructions. I have made them aware of this. It is unclear to me whether they can and will offer software updates. Downloading Data: The .csv file contains the time and sensor data for the entire time the system has been recording for that location. If I don’t do something to re-start history, the data file will eventually grow to unmanageable size. They should allow you to specify the range or use the range chosen for the graphing display. The file name is also fixed as the serial number of the unit. These are serious limitations given the extra work caused for the user, I consider them bugs. The data are separated by semi-colons, so converting from text to columns in MS Excel is easy. The data are recorded with a UTC time stamp. Since I’m in California, it is easy enough to subtract 7 hours and put the local time in the next column. The headers have a few character-conversion bugs: “μ” instead of “µ.” The character “” is inserted in the Temperature column header. These are minor. The date/time format is 2021-09-30T20:04:28. The “T” separator is a nuisance and prevents Excel from recognizing the form of the data. If they would replace the “T” with a space, then Excel would have no trouble. I use the replace function to do this. Again, it is no big deal, but should be a simple fix. I have made Airthings aware of these bugs. I will append this review, if I find additional information that may be pertinent to other users. I hope this has been helpful. Appendix 1: I've added a comparison of the PM2.5 data from the Airthings View Plus (indoors near an open window) to Purple Air data from an outdoor sensor (not mine) about 100 meters from my home. The Purple Air data are shown in the US and European scales. The data are for the 24 hours of October 29, 2021. Correlation is excellent for the main peak.

Update: We bought our Airthings View Plus on July 10, 2025, and used it as the hub for a Wave Plus and a Wave Enhanced. Great product—totally satisfied at first. In mid-September, the View Plus started reporting high CO₂ levels. The readings fluctuated but stayed in the Poor range and never dropped back to Fair or Good. I checked the Airthings website, which recommends placing the device near an open window and circulating fresh air to improve indoor air quality. I tried that, but the readings didn’t improve. To compare, I placed my Wave Plus next to it. The Wave Plus showed normal readings, but the View Plus remained unchanged. Something was clearly wrong, so I took pictures and contacted Don at Airthings. Don suggested a few troubleshooting steps and said if those didn’t work, we could try other options. I followed his suggestions—still no change. I sent more pictures, and Don asked for the device’s serial number and a copy of the purchase invoice. I sent the information, and within two days, he told me they were sending a replacement View Plus. They didn’t even want the defective unit back. The new device arrived within a week. I had a question about removing the old device, pairing the new one, and the impact on the App and website Dashboard. Don responded promptly. Replacement was easy-peasy. Airthings has fantastic product support—responsive and easy to work with. I highly recommend their products for monitoring air quality. They stand by their products and provide excellent customer service. Yes, they’re pricey and come from Europe, but they’re worth every penny. Great product. Great support. Highly recommended. Bought on sale along with Wave Enhanced for 2nd room. CO2 was the concern. Very happy with product and sale price. Customer service very helpful when asked about 5-year warranty registration and query concerning owners manuals. Manuals and comprehensive information are located on-line only, no .pdf's. When setting up hub be aware: Unit displays message HUB MODE ON, instructions do not say so, but this message only displays for 5-10 seconds. Consequently you might miss it and start over as I did, several times. Once done WAVE Enhanced connected. There is not much information on the HUB Mode in the product info description. Essentially it makes the unit and all units connected to it continuously available on-line via Airthings Dashboard. Airthings Dashboard, on-line only, very useful. Bookmark it on your phone for easy access. I like the product and would buy again. Customer service excellent and responsive. Struggled with initial Hub set-up.

Purchased Airthings Plus ($299). Worked great monitoring air quality in a fully finished basement where our teenagers spend time studying, watching tv, and having sleepovers. Out of the blue the device just stopped working. Screen displays horizontal black lines as shown in picture. I think Airthings pushed a software update that completely bricked the device. Called support and after practically zero troubleshooting, basically asked to replace batteries, they told me to buy a new one with no explanation. They are not standing by their product at all. Highly disappointed as I think they broke it with an update they pushed. UPDATE - March 2028 I have to admit that it is not often a VP of a company contacts you directly to address a problem. Airthings did exactly that and replaced my Airthings Plus with the latest model and software. VERY satisfied with the service and how they handled my situation. The new unit has been operating flawlessly since December 2025 when they sent me the replacement. We also had some work done in the basement over the winter and it was great to monitor the VOCs before letting the kids back down there. With this monitor we were able to see the spike and monitor air quality until it was back in the safe zone (about a week). Love knowing that my kids are safe and not being exposed to VOC, Radon, etc. Thank you Airthings!

Purchased this to track radon in our mostly-finished basement area. Wanted (1) A product that was wifi connected that could (2) track radon and humidity levels over a long period of time, (3) offered some kind of long-term dashboard/UI that was easy for human consumption, and (4) gave some level of warning if levels were astronomical. While spendy, this product was one of the only ones to check off all the boxes. I considered going with the bluetooth-only model to save money, but I'm really glad I didn't. The convenience of getting alerts from anywhere, seeing results any time of day or night is really worth the extra coin. I'll admit, Airthings really needs to work on their alerting system. Getting alerts about CO2 when working out in its vicinity, particulate matter alerts when cleaning, it's a bit annoying when the main alerts I want to see are radon and humidity, and I really wish they would allow you to set your own thresholds, but the smartphone app's UI and usability is exceptionally good and the product is easy to work with. My other nitpick would be battery life and/or no rechargeable batteries. The supplied batteries lasted for a solid 100-120 days or so. I replaced with my normal Energizer long-life battery and got maybe 75 days out of those before changing a couple weeks back to the next set. I usually can tell when the batteries are going because sometimes the results get a little crazy. I'd also like smartphone app alerts when the battery levels are, say, below 20% but I don't see that option. I mean, I'd love to just plug the unit into a power adapter and forego batteries totally, but I don't recall if it was an option on this unit, and batteries have sufficed. I may look into that later. Overall though, yes, it's expensive. But for constant monitoring, with alerts, to monitor all sorts of airborne levels, ACCURATELY, there isn't another product on the market I could find. I'm a satisfied customer, with a little polish in a few places, I could really see Airthings becoming a household name to the level that Ring and Nest have become. Great little product here!

Update (4 months after purchase): For the last few weeks CO2 readings were regularly elevated above 1.5k ppm, occasionally spiking above 2k ppm. I found out that the device needs to be regularly exposed to fresh air for CO2 readings to be accurate. It would have been better if there were some way for AirThings to detect and account for situations like this and adjust the estimate accordingly so it isn't overinflating CO2 values. I sent them this feedback. Original review: The AirThings View Plus seems like an accurate air quality monitor. For example, it easily picks up increases in CO2, PM2.5, and VOCs when I'm running on my treadmill in the adjacent room, more than 10 feet away. I like that the data is saved to the Cloud for easy export. When Wi-Fi is off, it stores the last 2 hours of data on a rolling basis. The only hitch in terms of connection is it seems sometimes when Wi-Fi is re-enabled, I need to enable Bluetooth on my phone and re-establish the Wi-Fi connection via the AirThings app, but this issue didn't happen every time. A minor inconvenience nonetheless. Allows for readings for multiple homes (e.g. different apartments), although I advise keeping the device in one home if convenient, because whenever a new home is started then calibration resets and a new segment is formed. Past segments remain exportable. Sleek, stylish design. Battery lasts months. Intuitive app. Weekly insight emails on the measured air quality. Measures radon which most air quality monitors don't. Overall highly recommend.

I was hesitant because of price and the description for their own products could be written much better. Everything seems to work well. Takes a week to get Radon and CO2 readings, but it seems accurate or agrees with other sensors I have, and the green/yellow/red alerts lights appear to be set at reasonable levels. Monitoring air quality can tell you much more about what happens in the house than for health and comfort. I use these devices to know when people have the furnace or air condition running with the windows open, and other things are awry once you know how the climate behaves in your house under certain circumstances. Bought a not much cheaper brand INK*** before buying this to replace an Awair, it was defective out of box and alarm lite indicators settings were not practical, so it was returned. Was using the Awair brand a few years before getting this Airthings, then Awair decided to stop supporting the product, so web interface and readings no longer worked. Awair offered to sell an updated unit at cost reduction, I was willing to pay but never happened - Never Awair again. This Airthings unit is same price as Awair products and Airthings appears of better quality, offers more readings and has a little more functionality with respect to the data. I think the display could be better, difficult reading in low light. Nice to have no touch, so less chance to get finger residue on it. Air quality monitoring product cost have skyrocketed in price (now that this is more popular), far more costly then cost to make, this Airthings unit appears to be the best buy for what you get.

I have had this unit for almost 2 years now, I will buy another. It literally saved my life! If you work from home, like I do, then you need this unit or something like it. I had Radon levels above 7pCi/L and had been living with it without knowing it, for almost 3 years. For those that don't know, Radon is a radioactive breakdown of uranium, thorium, or radium in rocks, soil, and groundwater. The CDC and EPA claim that levels above 4pCi/L are considered highly toxic and proper mitigation should be taken to reduce the levels. This is why Radon mitigation systems are installed in nearly every home across the United States. If you don't know, educate yourself about Radon and understand that radon causes over 21,000 lung cancer deaths in the United States each year and 2,900 of those deaths are people that have never smoked a day in their lives! For me, every now and then, I would cough and a small spat of blood would sometimes appear and i could never figure out why... Now, do you NEED this system? - Absolutely not, there are plenty of radon detectors out there and they are pretty cheap. Why do I recommend this system and why did I choose it? - Historical Data: This bad boy tracks all of your air quality metrics over time. This is extremely important when you want to understand cause and effect in anything in life. Many of the "bad reviews" talk about how some of the metrics displayed are inaccurate when compared to another device that specializes in one or many of the metrics this unit does display. Accurate comparisons only matter when comparing against a controlled environment and are purely for the sake of argument. This is important to understand because no unit needs to be 100% accurate, it just needs to be accurate to itself so that when you make a change, you can properly see that the change is affecting the metrics in a way that makes sense for what you meant to accomplish. For example, I had high radon (the value of the metric didn't matter other than the fact that it is higher than 0... it's radioactivity, is anything above 0 TRULY acceptable?) When I installed my radon mitigation system, I could watch my Radon levels drop tremendously over time, which proved that my radon mitigation system was actually working as expected! Also, I haven't had any spots of blood appear when I cough... I call this a success. - Dashboard: Airthings has a nice application and semi-customizable dashboard which makes viewing really easy to do, and from anywhere in the world. When my pets are home while the family is away, I can notify my neighbor to open a window to let some fresh air in, while we're away. - Alerts: Always cool to have alerts so you don't even need to "monitor" the metrics. Fun fact, CO2 builds up pretty rapidly in a well-sealed home. When you go through insulation techniques to seal off cracks and crevices to improve your HVAC efficiency in the thermal zone, it is easy to forget that CO2 has no easy escape. Needless to say, this little guy alerted my phone and I was able to crack a window and keep my family safe. I later installed a fresh air intake on my HVAC system and again, could watch the metrics historically, as they fell to a more than acceptable range, yet again proving that my air intake installation was actually doing its job. I hope this helps anyone looking to decide on this purchase. It has been an absolute godsend to have in our home and I didn't even get into some of the other things it helped me solve that had been plaguing us.

This product worked well. Mine stopped working short of the 2 year mark. AirThings advertises having a 5 year warranty if you "register," but, to quote their support team, "Simply adding the device to your account does not automatically enroll it in the extended warranty. Registration is a separate step and is required for the 5-year warranty extension to apply. If you do not register within 30 days, only the standard warranty applies." Be careful to register! In my case, because I didn't understand their special way of registering for the warranty, the company initially wouldn't replace the device. I posted a review sharing my experience, and to their credit they did actually reach out after that, and agreed to replace the device after all. Again, be careful to follow their process to register for the full 5 year warranty! (For those who don't know, maintaining a hidden, secondary definition of "registration" specifically to deny warranty claims is an unfair and deceptive business practice, likely in violation of the Magnuson-Moss Warranty Act among other state and federal laws. I'd give a full 5 star review if the product had kept working for me, or if they started their 5 year warranty period from when you register the device in their app. But, if you are careful to follow their warranty process, the product could work well for you.)

Un dans le salon et un dans la chambre. Je suis vraiment très satisfait, je n’en attendais pas plus, la qualité est vraiment au rendez-vous! Pour le Radon, il faut laisser plusieurs jours de calibration.

The Airthings View Plus has been an excellent investment for monitoring our home's indoor air quality. Our primary reason for purchasing it was long-term radon monitoring, especially to track seasonal variations and annual average levels. Based on our experience, the radon sensor appears to be highly accurate and reliable. One of the most valuable features is the mobile push notification system. We've configured custom thresholds for humidity, VOCs, CO₂, particulate matter, and other measurements, allowing us to react immediately whenever readings move outside our preferred ranges. The extensive alert and monitoring options are genuinely useful rather than just a novelty. It's also refreshing that purchasing the device gives you full access to its capabilities, historical data, and statistics. There are no paywalls restricting essential features or placing "must-have" functionality behind a subscription. It's also great to have full access to measurement history through the web interface in addition to the mobile app. Another major advantage is that the View Plus functions as a hub for other Airthings devices. We have paired it with a Wave Mini, and the two have worked together flawlessly for well over two years. Although the unit is normally powered by mains electricity, it also supports battery backup. We particularly appreciate that the batteries are reserved for backup operation rather than being unnecessarily drained during normal use. The power management has been excellent. The configurable measurement thresholds are flexible, the gesture controls on both the View Plus and Wave Mini are intuitive and convenient, and Airthings' customer support has consistently been friendly, knowledgeable, and helpful. The only unexpected behavior we encountered was related to the device location name. Renaming a location - for example, changing "Living Room" to "Lounge" - caused the historical statistics to be reset. We reported this to Airthings as a product improvement suggestion in 2024, so it's possible this behavior has since been revised. After more than two years of continuous operation, the system has proven to be exceptionally reliable. I can wholeheartedly recommend it to anyone looking for a comprehensive, high-quality indoor air quality monitoring solution.

I bought this to monitor the air in my 10x10ft room because I'm in it all day due to being disabled and in bed most of the day due to chronic pain. I'm on a lot of medication that makes me tired and so having good quality air in the room to help me from feeling tired is a necessity. I also need to monitor the air for particulate like PM 2.5 because of my asthma. I'm happy to report that this air quality monitor does all that along with VOC's, temperature, humidity, radon levels and for the possibility of mold. I was alarmed to realize that the CO2 levels were higher than outdoor air at 1637ppm (Should be 400ppm or lower). I have since opened the window in my room to air out the room and now I keep the window open a little bit to keep a constant fresh air supply into my room. I feel so much better already with how drowsy I am and the only change I made was making sure I get more fresh air. Homes today are so tightly sealed unlike older homes so they don't "breathe" and allow in enough fresh air on their own so these VOC's, pollutants, and CO2 can really build-up and make you not only feel tired but also be bad for your health. It really made a difference for me. I like that it can provide alerts to my smart phone via a WiFi connection so I know to open a window without having to look over at the air-monitor. I would suggest everyone get one. It will make a difference in your life and when it's on sale like it is now with Prime Day's it's a great price! Even cheaper than AirThings own website.

i've used this for a few months. its very good and accurate enough for home use. kept in kitchen. display is good. batteries first installed 9 months ago and still going strong. app is also good and informative for current and historical readings. worth the cost.

We have two of these, gives great insight into indoor air quality, amazing how quick co2 levels raise in our well sealed home. Nice app which graphs the historical results. Would highly recommend.
