When it comes to carbon dioxide monitors, there is one question I get asked more frequently than any other, and if you’ve read the title of this post, you’ll already know what it is. It is, of course, ‘What are the best affordable carbon dioxide monitors?’. While I’ve already partially answered this question in my article on the best carbon dioxide monitors, I thought discussing the topic in more detail would be great.

I’ve just updated this article to include the AirSpot CO2 monitor (full review here: AirSpot Review - A Tiny Carbon Dioxide Monitor That Can Be Worn as a Watch!) as I believe this monitor deserves a place here!

I also added mention of both the AIRVALENT TravelLite and Livegrid - two more devices worth noting!

Small update regarding my Qingping lite. After 9 months it is completely beoken. One month before the internal battery broke than it started to work randomly when plugged and now it is dead.

Beside useless temperature and humidity sensors (using offsets does not help) the reliability is very questionable.

Regarding temperature and humidity there are some 5-10Usd no name Chinese that are quite accurate this nvwu
Tuya WiFi Mini Temperature Humidity For Smart Home Thermometer Hygrometer APP Remote Alarm Work with Google Home Yandex Alexa - AliExpress 13 Have it for 7 months without changing the battery it is impressive. Same values like inkbird ith-21-b. I think to replace my qp lie with something from inkbird, they seam to be reliable and to have great temperature and humidity sensors. Thank you for reviewing iam t1.

I am not surprised to hear that the battery stopped working (this seems to be quite an issue with QP monitors), but I am very surprised to hear that the device stopped working entirely - that is very poor.

I wasn’t aware of these devices (especially not for such a low price!). I will have to check these out.

I think INKBIRD is generally pretty good and I haven’t yet had any bad experiences with their devices (except for the 9-in-1 monitor which was pretty bad). With that said, I’ve only used four of their devices so far (but each of them still functions well!). I would be curious to hear what you think of the IAM-T1 if you get one!
