Can Air Quality Monitors Detect Mold?

Some air quality monitors can detect mold, but you can't rely on these measurements alone to check for mold. ... The type of sensor that’s going to pick up mold is a particle detector (electrochemical sensors and MOS sensors aren’t going to do the job outside of a lab setting). These sensors work by shining a laser through the air drawn into the monitor. Any particles floating in the air ...
