Formal indoor air testing is to close the doors and windows and then use an atmospheric sampler to sample and collect air samples, and the samples are taken to the CMA laboratory for laboratory analysis in a standard environment. The results of the test will be issued with a CMA test report, and those that cannot issue a CMA test report are false (CMA institutions are not allowed to issue reports other than CMA format, that is, all data reports are illegal and untrustworthy).
