Smart Air Quality Monitor with Indoor Thermometer & Thermo-Hygrometer – PM2.5, AQI, Temperature and Humidity Detector for Home, Office, Nursery, School, App Connectivity, 60-Day Battery Life

I suffer from acute sinusitis and allergies. This season in Texas has been especially bad, and I felt that I was not feeling any better when indoors, even after taking allergy tablets. I wanted to make sure that my home was not actually making the symptoms any worse so decided to check by purchasing an air monitor. This one had good reviews and was reasonably priced. It arrived quickly and took minutes to set up right out of the box. I also like the stand that came with it and the fact it has a magnetic back, so it can be placed on a fridge or filing cabinet if needed. I wanted something easy and simple to read, and this has just what I needed, temp, humidity, air quality index and particle measurements. Within a few days I had readings for all major rooms, and fortunately all were good. It was comforting to know that the air inside my house was good and not making the symptoms worse. A great little unit.

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 like the long battery life (in several modes), apparent accuracy etc. The battery seems to go > 1-2 weeks between charges in the periodic sampling mode. It would be better if it included either WiFi or Bluetooth connectivity to transfer or trend the data, but quite functional at this price point!

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.

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!

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.

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

J'ai ce petit appareil en fonctionnement depuis plus d'un an dans une petite pièce dédiée à mon loisir "résine" et il fonctionne toujours parfaitement bien. J'ai aussi un purificateur d'air très efficace et précis et le Temtop s'accorde bien avec le purificateur, les résultats de l'un et l'autre sont très proches. J'ai juste remarqué qu'il fallait l'éteindre de temps en temps et le remettre en marche pour une relance à zéro des données qui se rétablissent plus exactement après cette petite manœuvre. Mais cela ne nuit pas à son efficacité.

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.
