GF83.10-P-2128-02E Combination filter, function  

Function
The combination filter is a combination of the previously familiar dust and activated charcoal filters.
On the one hand 80 % of all particles with a size greater than
0.3 ,are filtered out, while 100% of all particles with a size greater than 0.5 and 100% of the pollen are filtered out.
In addition odors and pollutants are continuously held back by a large number of so-called splinter adsorbers distributed uniformly on an air-permeable carrier mat. These are then released in extremely low concentrations after a time.
The fresh air as well as the recirculated air are filtered.
