What is the filtration efficiency?

The FiiT®'s filters have a fine particle filtration efficiency of 99.91%. 

It will protect you from pollution, pollen, dust, urban gases and most existing viruses. The filter has also a layer of activated carbon to protect you from road odors such as exhaust pipes. 

Finally, this brand new range is composed of a brand new filter able to meet both these daily needs and this new mask, so the FiiT® filter is not compatible with our current Nano® range (Light, Sport).
