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).
