An inlet assembly (114) for an auxiliary power unit (100) for an aircraft, including a duct (172) configured to provide fluid communication from an environment of the aircraft to an inlet of an engine of the auxiliary power unit (100), and a filter (182) received in and extending across the duct (172). The filter (182) includes a first filter portion (184) permeable to air, positioned across only part of the duct (172) and defining a transverse edge (190) in the duct (172); a second filter portion (186) permeable to air and extending from the transverse edge (190) to an end downstream of the transverse edge (190), and a collection member (188) impermeable to water. The collection member (188) extends between the downstream end and a duct wall. The first and second filter portions (184, 186) are non-parallel and the second filter portion (186) and the collection member (188) are non-parallel. An auxiliary power unit assembly and a method of feeding air to an internal combustion engine are also discussed.
