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

I have three of these, one for each of the floors in my home. It wasn't cheap, but I wanted to understand level by level how my air quality and radon moved throughout my house. It's been really insightful to see how cooking on the main floor affects the other floors, and see the radon start in my basement and get trapped on the top floor by my HVAC when it kicks on. Having the app and online historical data also allows me to see how pressure affects radon when the weather changes and how opening a window in the basement affects the other floors in the house. Lastly, the alerts are really nice. At some point you'll stop checking the app every 10 minutes and you'll get an alert letting you know that VOCs have spiked and you'll realize you didn't turn on the fan when cooking. Those little things all help you understand air quality and correlate your actions/items in your house to changing air quality.Overall I'm very satisfied and love the Airthings View Plus. I use all of them as stand-alone reporting, and none of them are hubs. The one thing that I've been disappointed with is the battery life. The batteries it comes with only lasted 6 months in the two units that are further away from my wifi, and the third unit that's very close has about 15% battery life currently and is 7 months in. So I suspect it might last 8 or 9 months if I'm lucky. I put better Duracell batteries in for replacements, so we'll see if that makes a difference, but I was hoping for at least a year out of them. I'll update this review maybe when they're at 50% battery life on the more reliable Duracell batteries with their projected life span.I've recommended these to a lot of friends and family. There may be a little more accurate units with sensors in them, but for ease of use, reliability, and consistency... I'd definitely buy these again.10/31/2023 Update. Everything working as expected. I continue to appreciate this purchase. Of the two units that are further away from my wifi, their batteries are dead again, giving me about 7 months out of the Amazon Basic batteries I put in them. I noticed that Airthings added an option within their settings for Battery Life Extension. They can now send data every 60 minutes vs every 10 minutes. They project this will give you 36 months of battery life vs "8 months of battery life" with sending data every 10 minutes. I appreciate this option and it seems they have adjusted their battery life expectations to something more realistic and that aligns with what I'm experiencing.

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.
