Use of a particulate adsorption material in the form of a globular activated carbon to extend the use and / or the useful life of an adsorbent filter unit, in particular to improve and / or increase the stability and / or resistance of the unit adsorbent filter with respect to biological contamination and / or against biological attack, wherein the filter unit is endowed or well equipped with at least one particulate adsorption material in the form of a globular activated carbon, wherein the carbon active has a total Gurvich pore volume in the range of 0.15 cm3 / g to 3.95 cm3 / g, where at least 60% (i.e.> = 60%) of the total Gurvich pore volume of carbon Active carbon is formed by pores with pore diameters of at most 50 nm (that is, <= 50 nm), in particular by micro- and / or meso-pores, and where activated carbon exhibits a hydrophilicity, determined as behavior static volumetric water vapor adsorption according to DIN standard 66135-1 at a temperature of 25 ºC such that at a partial pressure p / p0 of 0.6, with p0 representing the pressure under standard conditions (1,013.25 hPa), at most 30% is exhausted and / or used. of the maximum water vapor adsorption capacity, and / or that at a partial pressure p / p0 of 0.6 at most 30% of the maximum water vapor adsorption capacity of activated carbon is reached. |
