Plant air purification enclosure apparatus and method

This invention describes an insulated box designed to hold plants and microbes for purifying air. It draws dirty air from a building, cleans it using the biological elements inside, and then returns the purified air, also using thermal energy to keep the plants warm. The claims specifically detail a version that includes water sources for cleaning both the top and bottom surfaces of the plants.

Why it matters: Since 2011, advancements in automated plant care systems make the claimed leaf cleaning more practical, while improved building automation can better integrate its thermal and air handling aspects.
