Product Characteristic
Physical filtration compounds have been applied to the machine as the purification principle:
Pre-filters can capture substances in the air, such as hair and large particle pollutants; also help to extend
the lifespan of main-filters.
Main-filters are 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 has
been applied to the HEPA to inhibit bacteria to grow for healthiness.
