•Level of the Comprehensive Air-quality depends on particulate matter(PM10), ultrafine particulate matter(PM2.5) and gas pollution level. Therefore, comprehensive Air-quality level can be displayed differently from particulate matter(PM10) and ultrafine particulate matter(PM2.5) level.

-- Color of the Comprehensive Air- quality indicator will be decided based on worst status among particulate matter(PM10), ultrafine particulate matter(PM2.5) and gas pollution level. Which means that even though particulate matter(PM10) level is "Excellent", Comprehensive Air-quality will be "Lightly Polluted" if gas pollution level is "Lightly Polluted".

KKFor example, Comprehensive Air-quality will be "Lightly Polluted" (Yellow) when the particulate matter(PM10) level is at 10(㎍/m3), and ultrafine particulate matter(PM2.5) level at 40(㎍/m3), and gas pollution level is 3.

•When strength of the gas (odor) is fixed at constant level, Comprehensive Air- quality may not change even if the odor is strong.

•Value of the particulate matter(PM10)/ ultrafine particulate matter(PM2.5) level can be different from the forecast by the ministry of environment.

•Value of the particulate matter(PM10)/ ultrafine particulate matter(PM2.5) level can be different from other measuring instrument or product.

•Particulate matter(PM10)/ultrafine particulate matter(PM2.5) measurement will be displayed in 09~999.
