Abstract
(EN)
The present invention provides a three-dimensional filter for removing fine dust, which has excellent efficiency of removing fine dust and can be manufactured in a short process time by using a simple method and applying a low voltage. Further, the filter for removing fine dust according to the present invention: can remove fine dust in opposite directions so as to remove both fine dust coming from the outside and fine dust generated indoors; causes almost no pressure drop before and after filtering even when used in a flow condition; can be easily reused after being cleaned by a polar solvent; and has an excellent cycle property.
(FR)
La présente invention concerne un filtre tridimensionnel destiné à éliminer la poussière fine, qui possède une excellente efficacité d'élimination de poussière fine et qui peut être fabriqué en un temps de traitement court par l'utilisation d'un procédé simple et l'application d'une basse tension. En outre, selon la présente invention, le filtre destiné à éliminer la poussière fine permet d'éliminer la poussière fine dans des directions opposées de façon à éliminer aussi bien la poussière fine provenant de l'extérieur que la poussière fine générée à l'intérieur; ne provoque pratiquement aucune chute de pression avant et après la filtration, même lorsqu'il est utilisé dans un état d'écoulement; peut être réutilisé facilement après avoir été nettoyé par un solvant polaire; et possède une excellente propriété de cycle.
