Title
(EN) AIR FILTERING DEVICE
(FR) DISPOSITIF DE FILTRATION D'AIR
Abstract
(EN)
The present invention relates to air filtering devices for removing malodor and ethylene from the air. Such devices are useful for example for storing and preserving fluid in closed compartments such as refrigerators. The air filtering device of the present invention is characterized in that a first filtering member is capable of removing malodors from the air and a second filtering members capable of removing ethylene from the air.

La présente invention porte sur des dispositifs de filtration d'air permettant d'éliminer les mauvaises odeurs et l'éthylène. Ces dispositifs sont utiles, par exemple, pour stocker et conserver un fluide dans des compartiments fermés tels que des réfrigérateurs. Le dispositif de filtration d'air de cette invention se caractérise en ce qu'un premier élément de filtration est capable d'éliminer les mauvaises odeurs présentes dans l'air et qu'un second élément de filtration est capable d'éliminer l'éthylène présent dans l'air.
