Well made
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.

Buy it! The negative reviews are based on user error.
First, I wanted to address most of the negative comments here regarding the screen no longer functioning or the backlight is dim.This device comes with a usb-c to usb-c cable and no charging adapter. USB-c is generally higher voltage. This device uses 5v 1a. So what I suspect is happening is that the device overheats because of the extra voltage used in usb-c adapters. Also, although the device manual indicates that you can leave it plugged in all the time, it probably does not have battery bypass. The work around is to use a smart plug and charge the device intermittently. I do this for old phones to display weather, etc. by creating a routine that turns the device on and waits then off and wait again. Lithium batteries can be charged many times but it’s best to keep the battery level between 20-80%. The byproduct of constant charging is heat which will damage the battery. So those things should help the longevity of this device. The internal fan will also fail if the voltage is too high. With regard to accuracy and reviews showing 2 devices side by side with different values to imply this device is inaccurate. 1) you can offset the values to match any meter you perceive as being more accurate. 2) unless the device is in a controlled environment with a pre-measured amount of particulate, you will never get an identical number-why would you when you cannot account for the accuracy of the test environment? This is why temp and humidity are seemingly more accurate. That being said this device is very reactive and accurate. I have 2 analog hygrometers, 2 fans with controllers that have hygrometers, an Amazon air quality meter, and the thermostat on the wall. I have calibrated the analog meter by using salt like wet sand in a dish in a sealed bag. The meter is accurate when it’s at 75% where evaporation is equal to absorption. This meter is right on the money and the same is true with temperature. So unless you’re willing to spend about $15k for a “real” commercial certified air quality meter, this is about as good as it gets with some cool other features as well. The app works well on iPhone and I was even able to install a windows 10 version. Installing the sensor is simple. Research how to calibrate PM2.5 and other values before you decide about accuracy. I would recommend this device as it is reasonably priced and works very well. Amazon had a $24 coupon so I decided to get it and I’m glad I did.Update:Customer service is exceptional. They read my review and reached out and said the sensor causes heat (you can turn off the sensor in settings) and that the battery stops charging at 100%. However, in my opinion, it’s still receiving a trickle charge and you have constant charging while discharging. I would recommend a removable battery (they could charge extra for the optional battery) or a switch to stop charging. Also, i would recommend enclosing a charger and usb-A to usb-C cable and a warning not to use a quick charger or over 5v 1A because nobody pays attention to the input voltage even though the photos have a picture of the specifications.

App issues almost had me returning it.
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.

Terrible build quality for a $150 product. Lasts a few months.
Worked great for a few months. Usb C port now so loose it will not charge for more than a second unless propped correctly. Inexcusable for a $150-$200 product. Never moved it around, it just stayed in the same place so i swapped out the usb cable only a handful of times. No easy accessibility either, so self repair looks like a miserable task. Avoid.

Works great! Very accurate. I recommend it 🙂
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

Très satisfait de l’air moniteur dans sa première version. J’ai acheté le 2 également que je vous recommande.Cette version mesure le CO2 avec précision (comparaison avec le Aranet4 et Inkbird IAM-T1)les PM2,5 sont fiables y compris la mesure tVOC en comparaison avec les appareils Aranet et professionnels au travail.Autonomie moyenne mais plutôt fait pour un appareil de bureau. écran tactile ultra sensible et précis avec plusieurs fonctions. Application sert uniquement à la visualisation.les – :Ville pour l’indice AQI : très peu de ville française référencéestempérature et humidité : les mesures ont des décalages importants. humidité jusqu’à +20% et température souvent – 1,5° de moyenne. Mais je n’utilise pas ses mesures avec cette appareil. Sur le 2 ce problème semble être corrigé.Je recommande.

Havent used it yet, as the description doesnt make it clear its usb c to usb c not usb a to USB c
Naif –
disappointed battery life . With full charge it remain few hours. With such high price we should get much better battery
Julio C –
Me ha gustado mucho, la pantalla es una pasada, comparado con otros sensores se ve de calidad, y además es compatible con Home Assistant a través de MQTT. Muy bueno por este precio 129.
