| IAQ Level | IAQ Level signifies a level achieved through a single sample per room where the sample duration corresponds to industry benchmarks. A current calibration certificate is suggested for the meter used, and accordingly the IAQ level is accepted throughout the industry. |
| Published Standard Comparison (PSC) | PSC is reported against references listed at the conclusion of this report and meets both the required number of samples within a given area and required length of time sampled, so is in that sense consistent with the applicable Published Standards. See References section. |
| Air sample | An air sample submitted to IAQ analytics is taken using a 6 channel particle counter. Currently only data from selected handheld counters is accepted for assessment by IAQ Analytics. |
