Ubiflux Vigor W325/W400 Filter Set IC60% (G4) Pack Of 2

The air brought in from outside can be purified by two types of filters. The standard filter, used at normal dust content, is called a G filter. Do you have sensitive airways or are you allergic? So we recommend an F filter, a particulate filter. This type of filter removes 99% of dust and even pollen, mold and spores.
