I’m not convinced that the TVOC sensor included on consumer air quality monitors does much beyond give people anxiety. Maybe it’s useful if it prompts people to open their windows more often, but mine is so impacted by daily activity and subject to calibration drift to the point I wish it wasn’t part of my sensor unit. Opening a single bottle of beer will spike the levels for hours. It’s a super effective fart detector. I’ve had one for four years but I don’t know how I’d use it to determine whether some new product was harming the air in my home, the readings are just too noisy.
