A plant air purifier with filter material within a filter bed container, wherein the filter material can both allow air to pass through it during the unit's air purification phase and for water to submerge the filter material during its remoisturization phase The unit itself passes through various phases and sub phases: an air purification phase; followed by a remoisturization phase, which includes an immersion of the filter material sub phase, and a draining away of the water during its drainage sub phase. And in some cases, a soaking sub phase of the filter material for some time. Three different embodiments of the unit are provided: a unit with a separate soaking; chamber outside the unit; one with an outer pot surrounding the filter container; and one with a flapper below the filter bed container.

Disclosed herein are carbon dioxide capture devices, facilities, methods, and compositions. Specifically disclosed herein are devices, facilities, compositions and methods to capture carbon dioxide from the Earth's atmospheric air for providing long-term sequestration of the captured carbon and/or utilization thereof. To this end, a carbon dioxide capture device configured in accordance with one or more embodiments of the present invention can comprise a coating substrate having at least one coatable surface and a carbon dioxide capture coating composition on a coatable surface of the coating substrate. The carbon dioxide capture coating composition preferably comprises a coating material and a photosynthetic organism, wherein the photosynthetic organism is at least one of admixed within the coating material and on an exposed surface of the coating material. The coating material can deliver all or a portion of water to the photosynthetic organism necessary for sustaining photosynthetic activity of the photosynthetic organism.
