A device for filtering stormwater inside a storm drain includes a filter unit and a floating carrier for carrying the filter unit. The filter unit includes a bottom portion and a top portion. The carrier includes an axially extending recess for receiving the bottom portion of the filter unit, so that at least a part of the bottom portion of the filter unit is arranged below a surface of the stormwater inside the storm drain when the device is arranged therein. Through apertures extend radially from an outer surface of the carrier to the recess, so that stormwater at the surface can pass through the apertures and reach the bottom portion of the filter unit. Also a method for filtering stormwater inside a storm drain is disclosed.
