Is there an affordable air quality tester?

Question

We believe that we might have air quality issues in my office and want to test the air. Please let me know a brand name and about how much it would cost.

Answer 1

There is no single measure of air quality. Depending on what you want to measure the instruments required would range from the thousands to tens of thousands. If you live in a reasonably sized city you can probably find someone to do it for much cheaper.
