18-in-1 Smart Air Quality Monitor - Indoor WiFi Air Quality Detector with Dual Chip, Real-Time for AQI, CO2, PM2.5, PM1.0, PM10, TVOC, HCHO, Time, Temperature & Humidity with APP (White-White)

Very happy with my purchase. The monitor connected flawlessly with my smart home app.now I'm able to find out what causes me to have breathing issues at my residence. The display on the unit is easy to read and is easily controlled via the smart life app.

This unit is built well and feels like quality plastics were used. It monitors the air really well with a tiny fan inside to move air across it's sensors and I have bought 3 more for my fam to use in their houses. So that's 4 of these exact ones that i can personally speak to. One I have running for almost 4 months 24/7 and the 3 I bought I had running for 3 weeks before giving them away. I own 2 trusted other brand air monitors that I look to as a control group for testing. The 1 I own and 3 others all read the same correct values and react correctly to breath and particle mater testing, and having a neighbor blow smoke into them sends them into a orange and then red parameter level quickly. Great functions like audio alarm and HCHO and TVOC monitoring for volatile organic compounds (building materials, cleaning products, foams/carpets, paints and various smoke) is great! The Co2 monitoring is probably the most useful day to day reading to watch as it shows the build-up of of the gas we all breath out. Co2 at my huose is always highest in the mornings after sleeping, a good reminder to open windows and bring in fresh air. The app is user friendly and easy yo install but not needed for anything but screen auto-brightnes, wich is unavailable without the app. The daily operation and usability is unaffected by not having the app. Lays flat, can be wall mounted or stands vertically easily. Battery lasts about 5.5 to 6 hrs with the screen constantly on, or can be left plugged in. My experiences have bein excellent with this company's air monitoring products, I have 2 of their hand held units also and they too test well. Great value for what it costs vs what it does.

Worked fine for a while with realistic readings after calibration setup but now screen turns off every day. App is terrible so don’t really want to use app to view readings. No way to reset it. Basically junk now…

So far so good, it seems to keep up and accurate with my other air quality detector. Finding accurate quality reading air monitors is tough to find, but i think this one does a good job. I like that i can check my temperature and air quality when i am not home and turn on my air purifiers if needed through wifi also. I think this was a great value. I use this air monitor in my kitchen and i have a different brand air monitor that i use in my living room. I just like knowing the air quality in each area. As far as the battery, i leave mine plugged in all the time for constant connections and i leave the air monitor in one general area and do not move it so it stays accurate. I like the appearance and it is pretty easy to see and read. But time will tell how these hold up.

I'm so glad I went with this air quality monitor. It's very sensitive and picks up someone lighting a cigarette within seconds. I have a three level home and I tested it in all three as well as outside and it gave me different reading quickly. I ordered better quality air filters the same time as I did the monitor but the monitor arrived the day before. Around two hrs after I installed the new filters I was able to visually see the difference they made in my home on the graph on the app. The app is free to use and doesn't need a subscription & has the option to add smart devices. The quality is outstanding for the price considering how sensitive it is and I now know that my homes air was definitely contributing to everyone getting sick so often as well as getting random sore throats. I have 4 small children in my home and three are babies. The air quality in my home was very dangerous for them and I didn't even know until I purchased this monitor. It works and is very easy to set up. I can't say enough good things about it. I'm so glad I decided on this one.

Its not 18 sensor Smart Air Quality Monitor. The product itself is good but the seller claims date and time displayed is in that 18. Its at best 10 air quality parameters. My issue was there are products at half the price with 10 quality parameters.

I really like this product, though the screen is very thin and when I pulled the tab to take the film off, the screen started to move. Also the battery doesn't last 24 hours, so keep it plugged into a power source. But other than that it worked great. Setup was a breeze, I just used the QR code from the manual, downloaded the app, and then it synched up the time and date and the wifi settings. The colors are nice and I didn't do anything to set it up except change the units from SI to US. The display is very readable and the light level is adjustable in the app. This is a great value, and I highly recommend it. Some cons: The app wants you to subscribe to push notifications via SMS or some other thing. The max alarm levels could allow for higher values. My air goes between 0-500 AQI on a given day but the alarm max is 150 so I just disabled all the alarms except low battery. You can control the screen on/off and time out settings from the app. It's nice, because at night I like my bedroom to have zero light and this way I don't have to move it.

This product uses a simple setup for time and date. A precise seconds setup requires waiting for the 59 seconds to pass to click as 0 seconds occurs. The Temperature, CO², and Humidity are fairly accurate. The PM [1, 2.5, 10] are not working on my unit (see photo). The AQI, HCHO and TVOC sensors are also not working (See Photo). I was hoping this device worked.
