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