Checking Particulate Levels
To check the particulate matter concentration by
particulate size, press the Indicator button while
the appliance is operating.
• Press the button repeatedly to see the PM
levels displayed in the following order:
PM10 ~ PM2.5 ~ PM1.0
• The concentration for the selected particulate
size is displayed for about 10 seconds.
NOTE
• The overall air quality level is a result of both
PM concentration and the odor level.
• Even two products placed in the same space
could measure the concentration of particulates
differently due to air circulation.
• Unlike the odor level, the PM concentration
may take time to measure accurately due to the
slow diffusion rate.
• Due to the flow around the particulate sensor,
the displayed PM concentration and actual
concentration may differ.
• The PM concentration measured may differ
from the actual PM concentration in the
following cases.
− The presence of sofas, beds, carpets,
vacuums, humidity, smoke, fragrances,
cosmetics, perfumes, insects, or pets
− If the appliance is located near a construction
site, road, factory, doorway, window, or vent
− If the appliance is located near cooking,
humidifiers, sprays or other products which
generate steam or fine particles.
