I am looking for used air quality tools: particularly to measure dust in the home relative to outdoors… something like the Dylos Air Quality Monitor.
Perhaps you might have a nifty way to measure dust in the home such as placing a cloth Hepa filter over the register with the furnace fan on??? What about a bright light aimed at the carpet and then shuffling feet??? Do these make any useful sense?
I have a CO2 meter, boroscope, IR camera, and “mold kit” , etc
If you had a gas detector, that would be great too.
wish you a wonderful 2015
