Double cartridge design + H13 HEPA filter, double improvement from filter material to filter structure
F9 Initial filter
Base filter equipped with ProSeal® Technology
Benefited from the improved structure, the thickness of initial filter has been vastly improved by 50%, enlarging its dust holding capacity and is thus more enduring than its like products.
The base filter will effectively eliminate large particle pollutants like dust, hair and pollen.
H13 HEPA Efficient filter
Empowered by ProSeal Technology and layers of filter and carefully chosen antiviral H13 HEPA material, this filter can effectively capture allergen, germ, and virus,
meeting the strict demands of special environments like medical constitutions.
F9 Initial filter
Optimized structure, 50% thicker
Uses F9 filter material, effectively eliminates large particle pollutants like dust, hair, pollen
H13 HEPA efficient filter v2
Strictly chosen H13 HEPA filter material
Effectively captures ultrafine particles, e.g. germ, virus, tiny particles, with a purification efficiency of PM0.3 as high as 99.95%.
