Affordable&Reliable way to test hcho or tvoc

Thank you for creating such a great forum — I really appreciate it. I wanted to ask if there are any reliable ways to measure HCHO and TVOC. My office doesn’t have windows that can be opened, and I’m not sure if the new air system is actually working. I used a test kit and the result showed severe pollution, but I’m not sure how accurate that is. Are there any other instruments I could use to check?

Hi @zhenjq,

This is a great question!

Could I ask what test kit you used and what the specific results were? I ask because the test was likely already the most accurate way to tell, but it would be good to look into it.

I’m from China ,the package of test kit was all in Chinese, the result was really bad since the window from the office can’t be opened and the management might just turned their new air system to slowest mode?

Is there any suggestion including file a complaint to management office?
