Product Characteristics
Physical filtration compounds have been applied to the machine as the purification principle:
Plastic mesh filter: can capture substances in the air, such as hair and large particle pollutants; also help
extending the lifespan of main-filters.
Pre-filters: constructed by PET, Modified Actived Carbon and Transition Metal Oxides Catalytic to strengthen
the effect on odor removal.
Main-filters: constructed by HEPA (High-Efficiency Particulate Arrestance) and Modified Actived Carbon.
This combination can capture the size of solid pollutants above 0.3μm (Micrometer); also remove
decoration pollution, such as formaldehyde, methylbenzene and TVOC. An extra layer of anti-bacteria agent
has been applied to the HEPA to inhibit bacteria to grow for healthiness.

The measured value of PM2.5 from the unit is for reference only; the precision of the sensor can be
interfered by other appliances, such as humidifier. When the fan switches between high to low wind
speed, the reading of PM2.5 will fluctuate temporarily.
Note：
SMART mode will change its setting according to the air quality and brightness of the surrounding
