The present invention is an air purifier including an ionizing assembly that operates to charge particulate material in an air flow passing through the purifier. The charged particulate material is attracted to and retained by a filter element disposed downstream of the ionization assembly and having an electrical charge opposite to the charged particulate material. The purified air passing through the filter is directed out of the device, optionally in conjunction with a fragrance that is added to the purified air flow. The ionizing assembly is formed with a ground member disposed adjacent the ionizing member to keep the electrons generated by the ionizing assembly within the purifier, and thus prevent static discharges from occurring outside of the purifier. The air flow is directed by a fan through the purifier in an angular and substantially laminar manner, such that the efficiency of the purifier is increased.

La présente invention est un épurateur d~air comportant un ensemble ionisant, servant à charger un matériau particulaire dans un écoulement d~air passant par l~épurateur. Le matériau particulaire chargé est attiré vers et retenu par un élément filtrant disposé en aval de l~ensemble ionisant et ayant une charge électrique opposée au matériau particulaire chargé. L~air épuré passant par le filtre est dirigé hors du dispositif, éventuellement en combinaison avec un parfum ajouté au courant d~air épuré. L~ensemble ionisant est constitué d~un élément de base disposé de manière adjacente à l~élément ionisant pour maintenir dans l~épurateur les électrons générés par l~ensemble ionisant, et empêcher ainsi les décharges statiques à l~extérieur de l~épurateur. L~écoulement d~air est dirigé par un ventilateur à travers l~épurateur de manière angulaire et sensiblement laminaire, de façon à augmenter l~efficacité de l~épurateur.
