The plants are disposed on a near-vertical matrix panel of porous or fibrous inert material, in which the roots of the plants are embedded. Hydroponic water trickles down the panel, keeping the roots wet. A fan draws the air to be treated horizontally through the panel. The unit freshens stale air in a room. It may be provided as a wall-mounted unit, or as a self-standing tower unit. <IMAGE> |
