Operation Features
Checking the air quality
You can review the current air quality from the display panel with the colour (reflecting the PM10 / PM2.5 /
PM1.0 / gas pollution) and the concentration level indicators.
• By default, the colour and PM10 / PM2.5 / PM1.0 level indicators reflect the PM10 concentration.
• Each time you press the Air quality [
] button, the current state is displayed in the order of PM10 →
PM2.5 → PM1.0. The PM2.5 and PM1.0 levels are displayed for 10 seconds, before automatically changes to
the PM10 level.
–
The air quality will be ‘Very Poor’ when the PM2.5 / PM1.0 levels are worse than the PM10 level.
If the concentration levels are same for all PM groups, the indicator will reflect the PM10 level.
