I’ve been asked about this inexpensive CO2 monitor many times, so I finally decided to pick one up to see if it’s better than the Vitalight (another affordable option). I paid a total of $34 for this, so I’m hoping it’s at least accurate because it could be a compelling budget option!

Finally! I built & tested an open-source concept model air purifier that should be good for schools. Lots of air (CADR > 420 CFM), quiet (<45 dBA), uses <9 W, and ‘cause it’s wall-mounted & down-blowing, it moves air in the right direction & takes up no floor space. Always check my ALTs🧵⬇️

I’ve been super busy with work, so I haven’t had as much time to write recently, but I am currently working on a full review for the ultra-compact Airspothealth CO2 monitor.
This monitor is so convenient to carry around, and I love it for that reason.
