I have reviewed this article before. I have an office in a 12x24 portable building that I have carpeted, paneled and air conditioned. It has a love seat, armchair and pressed wood furniture along with a stereo, 50 inch TV, computer and router. It's a cramped building and I was wondering about the VOCs and carbon dioxide that can build up. I got this meter from Amazon and the CO2 monitor from another source. My test consisted of using a high speed fan to completely replace the air inside - I ran it until the CO2 levels were the same as outside. Then I set up both counters and started recording. None of the tools can register, so I had to do it manually. Based on my research, my maximum allowable levels are CO2 = 1000ppm, Formaldehyde = 0.12mg/m3 and VOC = 10mg/m3. Based on my findings, I void every morning (about 10 minutes). I then monitor the CO2 level until it reaches 1000. That depends on how many hours I've been in the office, the outside temperature, etc., but it usually happens in the late afternoon. During this time, as the graphs show, formaldehyde and volatile organic compound levels never approach my limits. Then I repeat the procedure. Much better would be an air conditioner that supplies outside air. They used to be commonplace, but today they are hard to find due to energy efficiency requirements.
