Smart Air Quality Monitor - Indoor Air Quality Meter with PM2.5, AQI, Temperature and Humidity Detector for Home, Office or School, App Connectivity, OTA Updates, 60-Day Battery Life

Wow, what a cool and easy to use device! I bought it because I am concerned because we live in the approach corridor of a major airport and I wanted to know how the incessantly flying airplanes affect the air quality. The device works right out of the box. Switch it on and it give you a number for the microparticles (PM2.5) and the air quality (AQI) pluis temperature and humidity. The two settings you can chose are F or C and how often you want it to make a measurement where you can go from real time (always) to every 30 minutes which obviously saves battery life and also the lifetime of the device itself, because these work with a laser that wears out after three four years. You can charge it with a standard USB C cable that is included, I have it running now for a week and the battery still shows five bars, even if I have it on measuring every five minutes. The best thing is that it is so small you can bring it everywhere and that's what I will do because I am also concerned about the air quality in hotels. And the second best thing is that it costs less than half of the fancy devices that you uselessly can connect to your Alexa. And by the way, our air quality is pristine, the PSM are in the single digits and the AQI rarely is ofer 15. I am relieved.

This air quality monitor is accurate, easy to read, and very helpful for understanding indoor conditions. It responds quickly to changes in the environment and gives clear, reliable readings for everyday use. The build quality feels solid, and the interface is straightforward. A great tool for keeping track of air quality at home.

Good value for the price. Works well.

As an immunocompromised traveler, I appreciate having AQI, temp, and humidity info at my fingertips with this compact device. It quickly displays AQI, works quickly & seamlessly with purifiers, and its design is space-saving with a magnetic back.

I was told by my pulmonologist to buy some hepa air purifiers for my allergies and asthma. While researching those I came across a review where the commenter mentioned she bought an AQI to test if the air purifier works well. Now I never heard of something like this existing - I thought you would have to hire a specialist to come out and test for things like this with expensive professional equipment. If I had known about an AQI before I would have bought one ages ago. I've seen a lot of criticism about the battery life, but there are actually 4 settings. When I first got the device I put it on the R setting (test every 2 seconds) and walked around each room of my apartment to see what the air quality actually is. This setting uses the most battery power and I don't like it because the numbers swing wildly and it's confusing. I tested out other settings as well and decided to keep it at A. While on A the AQI remains fairly stable. I recieved my device almost a week ago and the battery is at the halfway point. How do I know this device is accurate? The AQI remains mostly in the single digits, but when I light a cigarette the device can go as high as 80. I was shocked, I had no idea it was that bad. This gives me something to think about...... One last thing - my car A.C. is running cool not cold like it should. I already took it back to the mechanic twice after paying 2k for a total rehaul. The mechanic insisted, on my 3rd visit, they tested the temp of air coming out of vents at 48 degrees. I knew this wasn't right at all because I'm sweating like crazy. One day I had to run errands in diff parts of town. I bright this monitor and put it on the console tray which is right above knee level. The kickstand included was so helpful! I drove to 4 places in 3 hours, about 60 miles altogether. After each stop i took a photo of the reading (please note AQI is higher in 2nd photo because I smoked with the window cracked). The interior temp of my car never went below 90 (live in Arizona) and I plan to take my evidence back to The mechanic to prove they didn't do it right the first 3 times. Thank your for creating such a useful device at a great price!

Excellent product. High quality. Very easy to use. Very strong material.

Does what it says.... Checks air quality and relative humidity with accuracy. Simple to charge with a standard USB supply. Battery life depends on how many times the unit samples. You get four settings and can get over a month on a single charge with the lowest sample setting. Good quality product and for anyone worried about mould and high humidity levels in their room, you can now check at a glance.

A alguien más le pasa que siempre marca eso, en 3 lugares he estado y solo marca eso, o esta muy bien el ambiente en todos lados o el equipo está mal

Com menos de 2 meses de uso, soltou a fumaça mágica enquanto estava recarregando. Não recomendo.

Simple, small and useful. The batter last a lot. Being USB-C makes ir very convenient to me.

It does seem to provide pretty accurate PM2.5 and air quality readings. At least, these jibed with the one-word weather descriptions of Accuweather, a weather forecasting service. But will still need to try it out more to ascertain if it’s really accurate over a spectrum of air quality conditions. As of the first series of readings though, it did well.
