Does anyone have recommendations on an affordable “good enough” test tools for volatile organic compound (VOC) &/or #Formaldehyde

I’ve read about the affordable #VOC device shortcomings, but the local mold environmental specialist said doing professional VOC testing would be prohibitively expensive.

I don’t need it to be exactly accurate data as much as a warmer/colder: Did making [x] change help? Which areas are more or less safe? Thank you
