An air management device may include three independently operated primary impellers 131, 131′, 131″, and drawn-in air is discharged through discharge ports 15′-1, 15′-2, 15′-3 provided in the front plate 15 of the housing 10. Louvers 141, 142, 143 installed downstream of the air flow and discharge ports 15′-1, 15′-2, 15′-3 may be independently opened or closed to provide discharge of the air to the surrounding environment. Further, at least one retractable or pop-up fan may be provided. The air management allows customization of air flow. The housing 10 of the furniture-type air management device may be installed on the floor of the livable space and may have a hexahedron shape that extends from side to side. A bottom inlet 11′ may be formed on the bottom plate 11 of the housing 10 facing the floor of the living space above a predetermined distance. The replaceable filter 300 may be installed to filter the air sucked through the bottom inlet 11′, and may be drawn in and out of the housing 10. A plurality of passage openings 302 may be formed in a filter frame 301, and filters 320, 330, and 340 are stacked over the passage openings 302.
