Abstract

A hollow core door filters air flowing through the interior of the door between top and bottom rails of a perimeter frame and may absorb and decompose noxious or and undesirable materials used in the manufacture of door components and undesirable material in the air in the room or structure in which the door is located. The scrubbing action is accomplished by use of filtering material secured to one or both the top and bottom panels secured to the perimeter frame and to interior core elements. Air flowing within the door passes over the filtering or scrubbing material and the noxious material and gases are removed from the flowing air by the scrubbing material. Each of several embodiments of internal structural elements and materials allows for the flowing of the air to be cleansed and for undesirable materials or compounds to be absorbed and decomposed. Additional embodiments include absorbent material in the substances out of which door panels are made to absorb noxious material, and absorbent material within the hollow core for absorbing noxious material from the door panels themselves without including air flow elements, and exterior and interior photocatalytic materials.
