It has a triple-filter system:
1)Pre-Filter: the large-size pad filter can filter large particles of dust;
2)Middle-Filter: it filters the bigger powders for prolonging the main filter's life.
3)Main Filter: It includes HEPA(high efficiency)filter and gas filter. The HEPA cleans the gas and powders filering from the pre-filer and then carry them to the gas filter, which with the carbon and other chemical combination, filters off the deleterious substance and then outputs the clean air.
