Review on IAQ Mini CO2 Desktop Monitor by Rob Rogers

good CO2 detector. The biggest source of CO2 is our exhalation. Closing windows can lead to deposits. This allows you to control how much ventilation you need in your home. I am sensitive to high levels of CO2 and it makes me dizzy. I try to keep the level below 800ppm compared to the 450ppm found in nature. Put it in your bedroom and you will be very surprised. unless you get really close to him. I like universal USB charging. Not much documentation, but again this is a basic gauge. Impressive meter, a bit pricey but worth it for the larger display.
