A stormwater filter 2 comprising: a vessel 4 having an inlet 18 and an outlet 20; and a screen 22 disposed within the vessel 4 and arranged to divide at least part of the vessel into an upper section 26 and a lower section 24. The stormwater filter further comprises: a flow splitter 38 positioned adjacent the inlet 18 of the vessel 4 and/or a substantially vertical screen 32 disposed adjacent the outlet 20 in the upper section 26 of the vessel 4. The flow splitter 38 comprises an inclined leading edge 40 and first and second deflecting surfaces 42a, 42b extending from the leading edge 40. The first and second deflecting surfaces 42a, 42b are angled relative to one another so as to direct incoming flow laterally away from an axis between the inlet 18 and the outlet 20. The vertical screen 32 comprises first and second screen portions which are angled relative to one another. The first and second screen portions are each hingedly connected to the vessel and are detachably coupled to one another at their distal ends.
