I bought a fairly expensive air quality monitor. Accuracy wasn’t what caused me to go with a more expensive model. I wanted CO2 readings, which most models under $200 don’t provide.

I suspect I know exactly which one you bought ;) I wish I could find a good source for "outside CO2 levels" as I think they've been elevated but I have no way to prove it (beyond my indoor sensor showing high).

  Aranet4 is the way to go. Tried going cheap and getting a bunch of Vitalights later as additional monitors but ended up finding out that their results were all over the place. Returned the Vitalight. Kept the Aranet4. I do have plans to build a few Airgradients when I have time.

      uf, looks so ugly. I can't justify putting this into my home.

        it's a box? You could put a sticker on it, bedazzle it, or paint it with nail polish if you want something fancier.

Airgradient's kit has CO2!

can you share which one was it? I'm also looking for one, and CO2 is surprisingly uncommon. I'd also love for it to be HomeKit compatible, which makes it nearly impossible

  I have the Airthings view plus. It measures PM2.5, PM1, CO2, VOC, Radon. It was kind of expensive but I am happy with it.
