Since I made this video, I've had a chance to review the SmartAir CO2 Monitor. This is an inexpensive monitor (around $70), that offers almost all of the features of far more expensive monitors such as the Aranet4 Home and INKBIRD IAM-T1. It's also worth considering if you want a CO2 monitor! breathesafeair.com/smartair-co2-monitor-review/
I bought my ARANET4 on July 17, 2022, and I just checked the battery life. It has roughly 30% battery life remaining on the stock, included AA batteries. Absolutely incredible battery life and features!
Re: internal rechargeable battery vs AA batteries: lithiums are more compact usually, and the battery case itself won't take up any space, that's a plus. But if it can run on rechargeable AAs, that's a win in long term too: you won't have an internal battery that maybe hard to replace, or can't be replaced without damaging the enclosure. Of course it doesn't run on rechargeable AAs, because of the lower voltage, that would be a shame...
Thanks for review! Ended up ordering INKBIRD IAM-T1. Regarding rechargeable batteries, since many years I use rechargeable AA or AAA batteries from amazon, so it's not really a factor.
Thanks for the review! Will use your affiliate links. I wonder what are your thoughts on airthings view plus (seems quite pricey) and Qingping Air Quality Monitor (not sure how accurate are readings).
The problem with the AirThings meters (including the View Plus), is that they are still using fixed forced autocalibration on a 7/8 day cycle, making them nearly useless for home use where it never gets close to baseline (420ppm) during a normal week.
@@Breathesafeair that's what they say but you can't be sure unless you open it up. Maybe it's not NDIR and that's why both of them are a little "conservative" as you put it.
Hi, good research. Have you ever tried any Tuya device? I am using one with the Tuya app compatible it’s a cheap one (~30USD) not sure if the sensor good or not.
Hi, I haven't used this device but if it uses a NDIR sensor it is likely accurate. Is there any mention of NDIR or non-dispersive infrared on the website/marketing materials where you purchased the device from?
In a mostly closed purse or bag, or a jacket pocket, is an Aranet able to measure the carbon dioxide? Or does it need to be taken out completely? It is very expensive, so I am afraid it would be lost or stolen if I leave my bag zipper open all the time.
The company says that the air intake holes (on the back, top) need to be exposed to air for accuracy. I've got an Aranet4 and often keep it in my pocket (usually thin slacks or jeans). I've found that when I take it out of my pocket, the reading doesn't change much, so I'd say it's pretty accurate, even in a pocket or backpack, as long as the material isn't that thick.
It is definitely a good sensor! I didn't really discuss the individual sensors in this video, but all of the devices use NDIR sensors which are capable of giving accurate readings provided they are calibrated correctly.
It's funny that you ask that because I just got notified by FedEx that my Airvalent monitor is being delivered today! If you follow me on Twitter or subscribe to my email newsletter, you will find out my thoughts as soon as I've spent some time with the device. Thanks for watching :)

A good CO2 monitor should be a staple in every household, similar to a fever thermometer. I purchased my first CO2 measuring device several years ago when they were still relatively unaffordable. Meanwhile, I also own a device from Withings, which unfortunately cannot be calibrated and, on top of that, has a much too long measurement interval. My preferred device remains the "TFA Dostmann AIRCO2NTROL 5000" because it features LEDs that allow for a quick assessment of the current status. The threshold values are also programmable, and the brightness of the LEDs doesn't disturb in the bedroom. The device is powered via USB and can be found at least in the German Amazon store. By the way, if your devices are displaying correctly, it's time to open a window 😉
You didn't really say how accurate the different devices are. At the very least put a bunch of them together in different environments and see which ones match.
If you check the full articles on my website you will find I've done just that. Long story short, they tend to provide very similar readings. Here are a few of the reviews so you can refer to them: breathesafeair.com/airvalent-co2-review/ breathesafeair.com/smartair-co2-monitor-review/ breathesafeair.com/vitalight-mini-co2-detector-review/ breathesafeair.com/inkbird-iam-t1-review/ breathesafeair.com/co2-click-review/
You mention data, but not which ones support getting the data from using your own program. The manufacturer's app or software is useless, and uploading data to the cloud is unacceptable. Just have it present a minimal webserver serving a json with the data. But which one's support something like that?
By your own program, you mean exporting the data so you can manipulate and graph it in whatever software you want? All monitors minus the Vitalight support that.
@@Breathesafeair I mean that I want my program to be able to retrieve the data. Having to manually export something is completely unacceptable. I want to be able to make an offline Home Assistant show the graphs.

What portable CO2 you can recommend that can synchronize data in the phone?

Have you used a CO2 sensor for outdoor?
exactly what I was looking for, thank you so much!
What are your thoughts on the AirGradient One?

@@larryseibold4287 I just finished a full review (breathesafeair.com/airthings-view-plus-review/) and had much the same issue.
Have you tested the Airthings monitor?
Not yet, but I would love to!
How do you know the Qingping monitors are NDIR? It doesn't say that anywhere on their website/amazon.
I contacted QingPing and they mentioned both the AQM and AQM Lite use NDIR sensors from either Senseair or Sensirion.
@@Breathesafeair that's what they say but you can't be sure unless you open it up. Maybe it's not NDIR and that's why both of them are a little "conservative" as you put it.
@@anonanon7368 Fair enough. I would offer to open mine, but I don't currently have either monitor on me. Once I have them again I will take a look!

Thank you very much! Super useful video.
What about co monitors?
I haven't yet had a change to test them, but it's definitely something I am interested in!
INKBIRD's T1 is a sensor from Sweden, I have this, it's very nice!
It is definitely a good sensor! I didn't really discuss the individual sensors in this video, but all of the devices use NDIR sensors which are capable of giving accurate readings provided they are calibrated correctly.
Have you had the chance to test the super small Airvalent monitor?
Price is close to Aranet, but looks a lot more mobile...
