npub1lgdkj7vcxxvwxs29rv7sf8s3ve0gurpswjr77h5aztq5tvqmgcuq3le4sf (npub1lgd…e4sf) If you don't need the itty bitty Aranet, you might be able to find a less expensive table top/desktop CO2 monitor just for keeping track of home air quality.

There might be models that bundle in sensors for PM2.5, VOCs and CO2, which is something to consider. The downside is getting less than optimal readings and not be able to do anything to improve them.
