Title
(EN) POLYANIONIC ANTIVIRAL FILTER
(FR) FILTRE ANTIVIRAL POLYANIONIQUE
Abstract
(EN) Polyanionic filters are described for the hygienisation of enclosed spaces, for use in air conditioning splits and air purifiers, or as materials for protective masks. The filters of the invention, which are installed in air conditioners and/or purifiers, provide effective air sanitation by retaining viruses through a specific electrostatic interaction with the viral particles.
(FR) L'invention concerne des filtres polyanioniques pour l'hygiénisation d'espaces fermés, destinés à être utilisés dans des séparations de climatisation et des purificateurs d'air, ou en tant que matériaux pour masques de protection. Les filtres de l'invention, qui sont installés dans des climatiseurs et/ou des purificateurs, fournissent une désinfection efficace de l'air en retenant des virus par l'intermédiaire d'une interaction électrostatique spécifique avec les particules virales.
