Excellent Air Quality Monitor
I’ve been using this 16 in 1 Monitor for a little while now, and I have to say I’m really liking it. The 7″ display is one of my favorite parts, it’s big, bright, and easy to read even across the room. It’s rechargeable, battery life is excellent.I like how everything is laid out clearly, so I don’t have to scroll through menus or guess at what I’m looking at. It shows so many different details at once, and I didn’t realize how interesting it would be to track all those numbers in real time.The setup was super easy and I had it running within minutes. It updates quickly and seems very responsive whenever there are changes.The design itself looks sleek and modern, so it blends in nicely whether I have it on a shelf, counter, or desk.Another thing I appreciate is how versatile it is. It doesn’t just stop at one or two readings—it gives a full picture across the board, including temperature and humidity, which I end up checking all the time. Having it all in one unit which is excellent, since I don’t have to look on separate devices.Overall, I think this is a really well made and good value, useful piece of tech. It feels reliable, gives me a lot of useful information in real time, and looks great too. Definitely happy I decided to get this one.

WE ALL NEED ONE
I always keep a CO2 alarm at home since it’s such a silent but serious danger. I came across this device and decided to try it out. What really amazed me was how many air quality factors it tracks—not just CO2, but also humidity, temperature, particulate matter, formaldehyde, and an overall air quality index. Usually, you only get this kind of info from outdoor public sources, so having it for indoors is super valuable. I was a bit hesitant because of the price and the product description wasn’t super clear, but since CO2 was my main concern, I’m really happy with the product and the sale price. Customer service was very helpful when I had questions about the 5-year warranty and owner’s manuals. Just a heads up—the manuals and detailed info are only available online, no PDFs included. When setting up the hub, be careful: the unit flashes a “HUB MODE ON” message for only 5–10 seconds, but the instructions don’t mention this, so I missed it and had to start over. This device has really helped me feel confident about radon levels—I have a mitigation system, and now I can actually monitor that it’s working. Plus, it tracks other air quality stuff too, which is great. We’ve had it for a few months and it works flawlessly. The display is clear and easy to read. For example, when the house is closed up and everyone’s in the same room, CO2 levels spike, but as soon as I open a window or people leave, it drops quickly. I trust its accuracy—it takes about a week to get reliable radon and CO2 readings, but they match other sensors I have. The alert colors (green, yellow, red) seem well calibrated. Monitoring air quality has taught me a lot about what’s actually going on inside my home beyond just comfort and health. For example, I can tell when the furnace or AC is running with windows open or if something’s off with the indoor climate. It’s especially handy when cooking—I know exactly when to turn on air filters or open windows. I love the easy-to-read display and how quickly it connects. The battery power option is a huge plus—I can carry it around the house easily thanks to its compact size. Highly recommend this, and it even looks nice sitting on my side table!

great
I’m really impressed with this air quality monitor. The 7” display is bright and easy to read, and it shows so many details clearly—CO2, PM levels, temperature, humidity, everything I need. It feels accurate and responsive, plus the alerts are very helpful. A great device for keeping my home environment safe and healthy.

handy monitor for everyday use
I first set this monitor up in the living room where we spend most of our time, and it immediately gave me a clear picture of what the air was like indoors. The screen is big and easy to read even from across the room, and I like that it shows multiple things at once like CO2, PM2.5, temperature and humidity. When I’m cooking or if someone lights a candle, I can see the numbers react in real time which makes it feel very practical.One detail I’ve come is the alerts. At night I sometimes leave the windows closed and in the morning it lets me know the CO2 level is higher, so I just open the window for a bit and it goes back down. It’s not loud or annoying, just enough to make me notice. The temperature and humidity display also saves me from checking another device.The body feels solid, the white color blends in nicely at home, and I don’t find it complicated to use. The only small downside is that the cable could be a bit longer if I want to move it around more freely, but that’s not a big deal. Overall it’s a great tool to keep track of air quality day to day, simple to understand, and really useful for the home.

Great for VOCs, mold maybe?
The VOC, carbon monoxide features definitely work. I haven’t been able to get the PM particle detection (for mold spores) to show a spike, even in areas where I strongly suspect there are some mold spores. That was my primary reason for purchasing, but still glad I bought it for the VOC visibility as I am choosing new home.

Essential!!!
This is such a great product to have. It gives so much information at a quick glance. Air quality is important to breathing issues. This lets you know when you should open your windows to air out your house for best breathing for your health! The humidity indicator lets me know when I need to turn on my humidifier or dehumidifier. The fact that its wireless and rechargeable is a huge plus. You can put it in any room regardless of available outlets. The instructions were really easy to follow as it was simply just turn it on and go! The unit seems to be really well built and sturdy. The screen is large and bright, easy to see in a well lit room or in the dark.

I already had a CO2 monitor with extra information such as the temperature and humidity. Although I did not really need it, it was a good accessory to check the current situation. This one takes it a step further with more air quality metrics.It has a nice design and a nice display. You can easily read the metrics from a distance at night or at daytime, but the brightness could have had a slightly higher setting for daytime. It has an internal battery so it works right out of the obx, but you should plug its USB port to make sure it works continuously and keeps its battery charged.It has a wide range of metrics, which feels nice. It has a color indicator to indicate the current air quality, using the worst of the metrics. It also has alarms when the quality goes bad, but to me, that could be a little disturbing, as the CO2 level would quickly go high when you are cooking, and the brief alarm notification can still be unnerving. The measurements seem fine from where the device sits, but I am not sure if they are correct all the time in all the places. The readings might quickly change if I moved it slightly, but within the same area, which does not sound right. In addition, I have no means of comparing the readings to determine their accuracy, but as I mentioned, some of the readings quickly change when you are cooking nearby.I have only two complaints. One is that it does not seem to stand as robustly as I would have liked. Its curved design is nice, but I feel that it can easily tip over with a bump. The second thing is that at certain angles from certain directions, the display lights cannot be clearly seen. It seems that if I place it somewhere high and look at the screen from below at a certain angle, the display lights look very dim. But in most cases, the display can be seen clearly when it is below eye level.Overall, we like it. It looks nice with its design, it has many quality metrics clearly shown on its beautiful display. Internal battery is of course a plus. It was not something we really needed, but it is now something we enjoy.

This air quality monitoring device is quite nice. I have several smaller cheaper units setup through the house and this is far superior to all of them. It displays quite a bit of information. It’s easy to read from across the room even with my diminishing sight. You can customize a few of the readings like temp and what not and adjust your time to how you want it to read. I don’t need to tinker with settings too much as I am pretty content with the data displayed as is. It provides several measurements that none of my other devices provide. It does a good job of alerting you if air quality issues arise. Very easily picks up on changes from cooking, outside pollution coming through windows, air conditioning system related issues etc… Even small changes within the room due to activities are picked up. It seems sensitive, and seems to update quickly. I have found it immensely useful in monitoring and adjusting the environment to help ensure air quality remains optimized. This isn’t really a decorative item I know, but it looks fantastic honestly. It’s a really rich and vibrant red with a clean digital display. It honestly looks interesting and I appreciate that it’s not an eye sore.Likes:- Plenty of different useful bits of data.- More features and information than many smaller units I’ve tried.- Looks great for what that’s worth.- Seems sensitive and quick to adjust.- Has been a big help in optimizing air quality in the space.Dislikes:- A longer cable for staying hard wired would have been great.

I really do like this, it has a lot of good information about the air quality and it is easy to read and easy to set up.This gives better readings than a cheaper one i have which is good.The only thing i don’t like is on the one I got the usbc port doesn’t securely connect to the usbc cables I have used so if it gets bumped the cable may disconnect. It has a battery which means it will stay on but the battery is more meant for power outages so it goes off after a while.

The main reason I got it was to keep an eye on CO2 and PM2.5 levels, and it seems to be really accurate. It has external sensors that hang out the side, and it reacts quickly to changes, like when I’m cooking or when a window is open. I even tested it with some incense, and it showed the air quality getting worse right away, which was a good sign that it’s working well.The display is big and easy to read, which I love. It shows all the important information at once – C02, PM2.5, temperature, humidity – without having to press any buttons. The alerts are useful, and it’s nice that you can mute them if you don’t want the beeping.It’s also super portable. The battery lasts for hours, so I can carry it from the living room to the bedroom to check the air quality without having to plug it in every time.Overall, it’s a great device for peace of mind. It seems pretty accurate and gives me a clear picture of what’s in the air.

This is an absolutely beautiful air quality sensor and display.It is powered by USB-C and it also has an internal battery that will run it for some time in the absence of power.The Display is clear and readable with colours that are both beautiful and meaningful; the system indicates the air quality situation by moving from green for “excellent” through red for “warning”. It suggests that you open the windows and improve ventilation when things get into the red.The device is controlled by four simple buttons on the back. You can set the time so that the display works as an accurate clock in addition to showing air quality data.In addition to humidity, time, and temperature, the device indicates CO2 levels, total volatile organic compounds, PM 2.5 particles, and formaldehyde levels, along with an overall assessment of air quality.
