Abstract: An air treatment device for conditioning air within a conventional toilet bowl includes an air treatment assembly and an automatic flush mechanism. The air treatment assembly includes a cylindrical housing mounted to the rear of the toilet bowl rim with the toilet seat and lid swingably mounted thereto and an air duct having a free end extending into the toilet bowl proper. A seal underlying the toilet seat contacts the toilet bowl rim when the seat is in a horizontal position. Included within the housing are fans which draw air through the duct and a carbon filter to treat the air drawn therethrough. A flush assembly includes a motorized arm having a free end attached to the conventional flapper found in the water tank of the toilet bowl. Upon powering the motor, the arm moves the linked flapper valve from its normal closure position which allows the water to escape from the tank and flush the toilet bowl.
