<p>The invention relates to a matlike foam material stock which is suitable more particularly for purposes of air purification and/or air filtration and can be used preferably for installation in ceilings and ceiling systems, walls and wall systems, air-conditioning devices, ventilation shafts, as building material or the like. The matlike foam material stock comprises a gas-permeable, more particularly air-permeable, matlike three-dimensional support, the support being formed as an open-cell or open-pore foam, more particularly foam material, and an odorant- and/or noxiant-sorbing material being taken up or provided in the support, the odorant- and/or noxiant-sorbing material being designed as an odorant- and/or noxiant-sorbing, more particularly odorant- and/or noxiant-adsorbing, sorbent based on discrete sorptive particles, the sorptive particles being fixed on the support, more particularly on the walls of the cells or pores of the foam, more particularly foam material.</p> |
