Abstract (en)
[origin: WO2022090958A1] The current invention concerns a process for ventilating a space or regulating the air quality in a space, where air is introduced or air is circulated via a ventilation system, with the air being brought into contact with sulphated polysaccharides. In addition, the invention concerns a carrier equipped with sulphated polysaccharides, and an air ventilation duct with such a carrier or with a nebulising installation with a suspension of sulphated polysaccharides suitable for nebulising. The invention also concerns the use of a suspension or aerosol with sulphated polysaccharides or the use of a carrier for regulation of air quality in a space, wherein viral particles present in the air are captured and inactivated.
