Title
(EN) AIR FILTRATION SYSTEM
(FR) SYSTÈME DE FILTRATION D'AIR
Abstract
(EN) There is disclosed an air filtration system comprising: a component comprising a photocatalyst; and an ultraviolet source arranged to emit ultraviolet light towards the component. The air filtration system may comprise a sensor, and the ultraviolet source may be arranged to operate in dependence on the sensor. The sensor may be mounted on the ultraviolet source.
(FR) L'invention concerne un système de filtration d'air comprenant : un composant comprenant un photocatalyseur ; et une source d'ultraviolets agencée pour émettre une lumière ultraviolette vers le composant. Le système de filtration d'air peut comprendre un capteur, et la source d'ultraviolets peut être conçue pour fonctionner en fonction du capteur. Le capteur peut être monté sur la source d'ultraviolets.
