*Longest video ever put on our channel, very proud and also a little concerned. But I stand behind every bit of this being ONE video- it'll make sense I promise.
This is my annual tour of the International Builder Show where I'm in a tiny minority of commentators who try to dig deeper than just saying 'wow cool' and in fact might piss some people off royally. Whether you get pissed or not, I hope you'll be interested in the deeper dive into the physics, chemistry, and microbiology we always try to bring to the table.

Testing using the Extech VPC-260 6-Channel Particle Counter, FLIR MR277, Aranet4 CO2 sensor, and Sensit P100 CO monitor.
