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.

The most comprehensive Air Quality Monitor
+ What I like best: 1. It measures accurately a lot of environment parameters including PM2.5, PM10 (dust), carbon dioxide (to know if room is ventilated well), temperature, humidity, noise and tVOC (volatile organic compounds); 2. In case some parameters are not correct, you can easily calibrate manually or automatically; 3. It gives you options to adjust manually all the parameters in case a certain parameters drift after a long time of using; 4. It shows you all parameters in one screen so it is very convenient! 5. You can also check the app if you are not close to the monitor; 6. It has built-in battery which lasts 4-5 hours so you can bring along to check outside environment.+ What I dislike: The battery doesn’t last long enough so you need to charge it on time; I hope the battery can be replaceable in the next generation

only caveat is battery life
Fantastic little device. Had it for close to a year now. Beautiful, clear little screen, well designed UI (though I wish the detail view with the larger info display cards was an option for the default screen!).My only gripe is that battery life is terrible! Needs to be plugged in at all times, as it runs out of battery within 4 hours or so. I assume the bright crystal clear screen is what is causing battery drain, so perhaps it could be good to have an ultra-dim mode, an option to put the screen to sleep (I usually only check the info a few times a day), or perhaps an option to reduce the frequency of air readings? Some possible options the manufacturer can hopefully consider, though I’m not sure if any would be enough to make the device possible to run longer than a day off power.

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.

seems to work properly
I can’t know for sure exactly how accurate the sensors on this thing are. However, it seems that the PM sensors, the CO2 sensors, the tVOC sensors, and noise sensors all respond as expected in certain situations. The PM sensors go up when smells from food cooking on the kitchen stove enter the room, although both the PM 2.5 and 10 readings always seem to be identical. The CO2 goes up after a night of sleeping with the door closed because, as a human, I exhale CO2. The tVOC sensors go up if there is a glass of beer or isopropyl alcohol in the room. Speaking or singing raises the noise sensors. So, I guess this was a fine purchase for my $150.

Great and reliable device.
This has been a great and reliable product. It has shown me that the bedroom I sleep in gets very high CO2 levels at night. Since realizing this I corrected the issue and wake up a little more refreshed and less stuffy feeling. Info with it was compatible with more smart home products and for that reason I will no purchase another one8-month update:After moving the device to my nightstand, I discovered a major issue. While charging, it produces a very noticeable coil whine. The noise is loud enough to make it nearly impossible to sleep until charging finishes.We experienced a power outage for a few hours, and when power was restored late at night, the noise was unbearable. It took a while to identify the source, but I eventually confirmed that unplugging this device immediately stops the sound. Plugging it back in causes the noise to return until charging completes.

Excellent and Accurate
Looks good and simple to use. “Consumer Reports” highly rates its measurement accuracy.

Cumple su funciónPero la batería sin conectarse dura solo 2-3 horas tiene que estar siempre conectado y cuando está conectado emite un ruido / pitido muy agudo que llega a ser molesto.

Zeer eenvoudig en overzichtelijk in gebruik. Nadeel is dat ie eigenlijk alleen bruikbaar is als ie aan de stroom hangt. De batterij gaat maar een paar uur mee. Nog geen ervaring met de waardes, weet nog niet of die betrouwbaar zijn.

Ich nutze den Air Monitor im Wohnzimmer und im Büro, in dem auch ein 3D-Drucker steht. Genau dafür habe ich ein Gerät gesucht, das zuverlässige Sensoren hat und nicht nur „Schätzwerte“ anzeigt.Besonders überzeugt mich der CO₂-Sensor (NDIR) und der PM2.5-Sensor. Die Werte reagieren plausibel und reproduzierbar: Beim Drucken (PLA/ABS), Lüften oder bei mehreren Personen im Raum sind die Veränderungen klar nachvollziehbar. Keine sprunghaften Fantasiewerte, sondern saubere Übergänge. Temperatur und Luftfeuchte passen ebenfalls gut zu Referenzmessungen.Das Display ist sehr gut ablesbar, die Aktualisierungsrate sinnvoll gewählt (nicht nervös, nicht träge). Die App ist funktional, übersichtlich und ohne Abo-Zwang. Die Akkulaufzeit ist zwar nur wenige Stunden, aber das ist für mich kein Problem, da er ständig an einem USB-C-Kabel angeschlossen ist.Für alle, die echte Luftqualitätsdaten wollen, gerade auch im Umfeld von 3D-Druckern, ein technisch solides und vertrauenswürdiges Gerät.

Amazing insights on what is happening (I was suffocating myself by closing door and/or windows. Now both stay open). And it does not require an account to use.
