This Aranet 4 is a useful and dependable tool for measuring CO2, humidity and temperature in a room. It works well, and the temperature is consistent with my thermostat. It is easy to carry when I travel, attend meetings, and even when I am driving. It works through netting. I recommend it. Fresh air is important!

Es fácil de usar y muy preciso.

I’m using this to detect whether or not my CO2 scrubber is working.
This device is unique for that purpose, in that the cheaper ones on Amazon can’t accurately detect less than atmospheric levels of CO2. (Less than about 400ppm). That makes those useless to me, because I’m trying to verify that the CO2 level is at or near 0.
This works great for that, and sends notifications to my phone if the CO2 levels change.
Maybe the only thing I’d change is that the warning and error levels for CO2 detection cannot be set lower than 350ppm. That makes sense for most uses. But it would be better for my cases if I could set it to 150ppm or even 80ppm.
But great hardware. Worth the money IMO.

I bought this to gather some data about the air characteristics in various rooms in my house.
It is easy to use. If you download their app to your phone, you can easily download the data it collects. It measures temperature, CO2, air pressure and relative humidity. You can set the interval, too. By default it was set to record readings every 5 minutes.
It uses batteries and only batteries for power. Some might prefer the ability to plug it in to avoid batteries. I would. However, I could not find an similar product that plugs in. Not a big deal though.
It uses blutooth to communicate with your phone. This seems to work flawlessly. I would prefer a wifi connection to my home’s router and network but also a minor issue.
My only substantial gripe so far is the inability to record any metadata in the app. For instance, what room it was located in during a given time frame. If I want to gather one weeks worth of data for my basement, it seems obvious to me I should be able to tell it where it is at a given moment to then include with the recorded data. It doesn’t allow for recording data like this, though, so I decided to keep a small notebook with it wherever I place it and log the time and dates of things like location changes. This way I can retrospectively make sense of the data.
Also, the memory is limited. With mine set to record the data ever 5 minutes, it stores 2-3 weeks of data.
Overall, it is a handy little device and I recommend it if you need it for it’s designed purpose. However, some minor improvements would really make this stand out.

Really happy with the product itself
GOOD: It is quite expensive but, at least, you are getting professional quality sensors for CO2, Temperature and Humidity.
BAD: This was apparently imported from the UK (awkward as the company is in EU…) and the delivery in France via Chronopost was awful: this EUR 200+ device was just dropped into the common mailbox for the building for any resident to pick up! no phone call / no ring on the door bell. Got lucky that I had a friend in the building picking it up for me…
A unpleasing experience quite rare with Amazon who usually are spotless in their selection of delivery partner.

The aranet4 is such an excellent monitor, and really is the best bang for your buck in an accurate and easy to use monitor. We have used this in all the rooms of our home to measure air flow and how quickly C02 builds up – especially useful in the kitchen during various cooking processes and in the bedrooms overnight – but we have also brought it to work to measure the C02 and get an idea of the air flow in various offices as well. It’s easy to set up, the battery life is excellent, and it’s easy to bring with you anywhere. The app works well and is likewise a quick and easy setup. We keep this monitor in the main living area of our house and it’s every easy to monitor when the C02 is accumulating and we need to crack a window or turn on an exhaust fan. It’s been illuminating. This item is also very accurate, and more so than others and cheaper version. Totally worth the money and a reliable, trustworthy device for monitoring a really important aspect of our health.

Although this sensor is not the cheapest one it is so easy to setup, you can use the designated app but it also immediately connects to Home Assistant Smart home.
Very stable connection, CO2 reading seems to be very correct, it has battery which last a long time.
Worth it’s money.

This thing is synonymous with accuracy. It’s pricey. But definitely well made. Solid. The e-paper display is crystal clear, and ensures the battery lasts a VERY long time. Not TINY, but portable enough to take around and check various areas for CO2 levels. The biggest offender for me so far? My car with the AC on recirc.

I have purchased 2 of these monitors because I liked them so much. There was no hassle during the set up; the monitor connected to the Aranet Home mobile app without any hiccups. The mobile app is basic, but it functions smoothly and gives me all the data I need (current CO2 levels, ability to query custom date ranges)
Overall, a great product I would recommend

So easy to set up and the factory calibration was already perfect. The app data is really good!
Extremely eye-opening experience using this device. I found out that I’ve been working in 1200-1600 PPM and sleeping in 1800-2500+ PPM conditions. I just cracked a window open slightly when I slept instead and I got my PPM levels below 900 at night… I slept much better and felt much better when I woke up! It’s great!

I got the SAF Aranet4 Home mainly because I was curious about why I’d get so groggy in one particular room of my house. This little gadget was easy to set up right out of the box and it immediately started giving me the lowdown on my air quality. Turns out, the CO2 levels in that room were off the charts sometimes – no wonder I felt like I was in a brain fog half the time.
I love that the Aranet4 is portable. I’ve taken it with me on trips, and it’s kind of become my travel buddy. It’s wild to see the CO2 levels on airplanes and in hotel rooms. The color coding on the device makes it super easy to understand when the air quality is getting bad, and the buzzer is a neat feature too, although I turned it off after a while because it startled my cat.
The app is simple and does the job. It keeps a record of the air quality data, so I’ve started geeking out on comparing the air quality in different places I go. The e-ink display is clear, and the battery just keeps going – haven’t had to charge it yet!
The Aranet4 is not just a fancy gadget; it’s been a real eye-opener for me. It made me realize how the air quality around us can affect how we feel. Now, instead of guessing, I know when to crack open a window to get some fresh air in. It’s pretty satisfying to see the CO2 levels drop and feel that mental clarity kick in. Honestly, in these COVID times, it’s comforting to have a better grasp on the air I’m breathing, especially in new or unfamiliar places.
So yeah, I’m really glad I got the Aranet4. It’s helped me understand my spaces better and take simple steps to improve the air quality around me. Plus, it’s kind of fun having this little gadget with me, measuring the unseen world of air quality wherever I go.
Update: have lent the device to several friends now to test their apartments, and they’ve all found ways to improve their air quality!

Was looking for a CO2 monitor for some time and this does the job nicely. Being portable means I can have it in my study while I work or move it to the bedroom while I sleep, readings correlate pretty well with when I’m feeling groggy from being in the same room too long without opening a window and it has helped me feel clearer headed.
The eink display is pretty easy to read and should mean the battery doesnt drain too fast, It transmits its updates over BLE meaning homeassistant picked it up immediately without needing to be paired. App is straightforward and allows you to adjust a couple of settings as well as update the firmware. And it works locally so no accounts needed for the device or app.

Much smaller than I thought. Easy to operate and reliable, stores data for a 14-day period, which can be displayed later in the smartphone via Bluetooth. Helped a lot to improve the air conditioning in my bedroom.
