Room air purifier
First Claim
1. A soil bed reactor room air purifier comprising:
- a base;
a container having an upper chamber retaining a layer of soil containing aerobic microorganisms, and a lower chamber retaining a water bath;
means for fitting the container on top of the base;
means for drawing air from a room into the base; and
means for passing the air from the base into the container and through the water bath, then through the layer of soil and discharging the air into the room.

Abstract
An indoor air purifier has a base and a container on the base with a layer of soil supported above a lower water bath occupying the bottom of the container. The container is fitted on top of the base such that the container can freely rotate upon the base. Room air is drawn into the base and is passed from the base into the bottom of the container through a duct connected between the two. Air passing from the base is directed downwardly into the water bath before passing upwardly into the soil layer. The air passes through the soil layer and is discharged from the soil'"'"'s surface back into the room. Contaminant gases and particulates are removed from the air through contact with the soil layer and are metabolized by microorganisms contained within the soil, producing carbon dioxide and water. The water bath humidifies the air being passed through it and maintains a stable degree of moisture in the lower portion of the soil layer. Water lost through evaporation is replenished through a sleeve passing downward from the soil'"'"'s surface to the water bath. A water bottle inverted within the sleeve maintains a substantially constant water level. Plants may be grown in the soil layer to aid in purification and to provide an attractive room decor.

27. A soil bed reactor room air purifier comprising:
-
a hollow base; a circular rail around a top of the base, the rail being divided into a plurality of circumferentially extending segments leaving gaps between the segments for passage of room air; a plurality of openings in the top of the base inwardly from the rail for introducing room air into the base; an open top container on top of the base; a circular groove in the bottom of the container complementary to the rail on the base for permitting rotation of the container on the base; a retainer plate in the container above the bottom of the container; a layer of soil on top of the retainer plate containing microorganisms for metabolizing vapors carried in room air; a bath of water in the bottom of the container; a central duct between the base and the bottom of the container, the top of the duct being above the level of the water bath; a blower in the hollow base connected to the duct for passing room air into the duct; a cap surrounding the duct in the bottom of the container for deflecting air from the duct below the surface of the water bath; and openings through the retainer plate for passing air from the water bath into the lower portion of the layer of soil. - View Dependent Claims (28, 29, 30)
