A room humidifier and air purifier withdraws air from ambient room atmosphere into a region having a living plant with its roots in a growing media of highly adsorbent activated carbon and zeolite; passing air preferably downward through such media and back into the air over hot light bulbs which destroy undesirable airborne mold spores. The light bulbs are also used to supply sufficient light for plant growth and aesthetics through indirect lighting on the plant leaves. |
