CO2, carbon dioxide, is deadly also. You can't smell it but you can feel it in your lungs in high enough concentrations. Except for oxygen, any gas will suffocate you.

This year I added a few Netatmo modules to my house which, among other things, monitors CO2 levels. It was a real eye opener to watch the CO2 levels. When my wife and I are sleeping in our bedroom with the doors and windows shut the CO2 level soars. Not quite into the dangerous zone but still very high. We now leave the hall door open a little and the levels are much lower. The same for my home office. It is a small, tight room and after I work for a few hours the CO2 level is so high that I now open the outside door occasionally to get some fresh air. Without the Netatmo I was completely unaware of these high CO2 levels. New houses have forced ventilation but my house is over 60 years old.
