When the air purifier
operates, press the
[

particulate matter(PM2.5)
level will be displayed for
10 seconds on the display.
-
However, ultrafine
particulate
matter(PM2.5) level
will be displayed when
the level exceeds
50
㎍

. When
ultrafine particulate
matter(PM2.5) level
is below 50
㎍
/m

the
air purifier will just
display the particulate
matter(PM10) level.
NOTE
• Surrounding environment (near
construction site, streets, in a room
where it is being vacuumed, or near
fabric sofa etc.) could affect the
particulate matter(PM10)/ultrafine
particulate matter(PM2.5) level.
• Particulate matter(PM10)/ultrafine
particulate matter(PM2.5) level can
be high in a place such as veterinary,
clothing store, or a place with a fur rug,
high humidity, smoke or bugs.
• If you use humidifier, electric pressure
rice cooker, or spray, it may affect the
particulate matter (PM10) level/ultrafine
particulate matter (PM2.5) and the level
may increase.
• Particulate matter(PM10)/ultrafine
particulate matter(PM2.5) level could
be consistently high in a region where
yellow dust storm (or sand storm) occurs
or in a environment where outside
air can easily get it (such as near air
conditioning vents of the building,
ventilation system or a window).
• Comprehensive Air-quality can be
affected by an air freshener, deodorant
or a detergent that causes odor.
• If you use more than one air purifier
in one room, products may display
the particulate matter(PM10)/ultrafine
particulate matter(PM2.5) level
differently due to air circulation.
