Qingping Air Quality Monitor Gen 2, Air Quality Monitor Indoor Detects PM2.5, CO2, PM10, Noise, Temperature and Humidity, New Upgraded Alarm Clock Function, Air Quality Tester for Bedroom, Smart Home

Unquestionably better than airthings. Wow. If you’re trying to decide this is amazingly better in so many ways (except lacking radon). The display is awesome and functional and easy. It has alarms, it has air quality and weather and beautiful time clock. The settings are so easy to set up. The cartridge loads in back and is zero noise. And it turns off the screen during sleep hours. It’s very accurate and updates frequently. It’s easy and nice looking to be able to keep it plugged in, and can simply sit on a table or shelf. Beautiful design. Perfect for by the living room or bedroom.

This is a great air quality sensor. I purchased one before my trip and used it on the trip and found it to be very accurate. If I spray some hand sanitizer in about a minute, then the VOC will start beeping.You can set an alert for a threshold for the different air quality categories, which is very handy and then you can tap a button to stop it.One time at night time the CO2 levels got high, so it beeped and so I knew that I needed to open a window. That only happened one time. It has a touchscreen which is really nice and it’s really easy to use right out of the box. The battery lasts probably three or four hours so I usually keep it plugged in and during the day I turn it off which I believe can save the life of the product because when I’m not home, I don’t really need it on so. It has this cartridge that you put in in the back and I’m pretty sure that probably has a life expectancy of that cartridge. Not sure how long it lasts, but I think turning it off during the day when you’re not home can extend the life of the product.It’s easy to turn it off just push and hold the button on the top and you can either reboot it or turn it offWhen I got back from my trip, I purchased another one for the home.You can also program it so the screen turns off between a certain time like when you’re sleeping, but it will still work while you’re sleeping.If you’re concerned about connecting it to your Wi-Fi, then you could just set up a guest network temporarily just so it can do a firmware update which will happen when you get it new out of the box and then it will set the timeAfter that, you can turn off the Wi-Fi really easily in the settings if you don’t want it connected to the Wi-Fi

This is a really nice air quality monitor. It feels sturdy and of good quality. So far, it’s accurate with our air purifier readings. Easy to initially set up, basically, plug in with your own power cube (cable included but no power source), turn it on, and it goes into sensing almost immediately. The manual is rather vague and gives no real details like how to change time to 12H, Temp from Celsius to Fahrenheit, etc. Some Googling did not help much, but exploring the screens and settings finally got me past that hump without any help from the manual. Speaking of the manual, it’s mostly in Chinese. Some information in back section in English. I would not suggest the QR Code for App in manual!!!!!. It’s terrible, tries to get you to onboard all home automation (which I was not going to do for this Chinese Company) and initially would not work except for in Chinese. Finally found the app to use from Amazon info. As “Qingping+”. That helped a lot. Able to check and change information for units by app or on the units very nice, sharp, and nice looking screens. Touch screen works beautifully.

I've had both the original model and this one, they work great. If I put them together they agree on PM2.5 measurements and CO2, within error bars, and with my Aranet 4 CO2. If I put them outside, they'll also agree with other measurements of outdoor PM.Battery is like 3-4 hours, fine for moving around the house (try putting it in the kitchen when you fry food), but it's not designed for all-day portability. (Also... look at the shape. It's designed for good visibility on a desk, not being put in your pocket or even a bag.)A few flaws: I'm not sure the VOC readings are all that meaningful or useful; I've seen people say that good cheap VOC sensors simply do not exist. On this newer model, PM10 pretty much follows PM2.5 all the time, which I'm skeptical of; I've also seen people say that good cheap PM10 sensors don't exist. The internal fan is pretty quiet, but if you have sensitive ears and are in a silent room, you may detect it. Finally, this newer model sometimes drops off the net (I use the phone app to check on my monitors from outside the room or even house), and the only fix I've found has been rebooting the monitor; not a huge problem, but a bit annoying.
