Abstract
A smokeless ashtray includes an ashtray that is formed with an ash receiving cavity and air passageway. The ashtray is supported by a housing having an upper portion which forms an air intake substantially adjacent to the ash receiving cavity, and a bottom portion which removably receives the ashtray. The bottom portion also includes a motor filter receiving space and is formed with an exhaust aperture. A motor is mounted within the motor filter receiving space with a fan being connected thereto such that the fan is located below the ashtray. The smokeless ashtray also includes an ashtray filter and/or a motor filter. The air passageway of the ashtray is configured to receive the ashtray filter while the motor filter receiving space within bottom portion of the housing is configured to receive the motor filter. The fan creates an air flow by drawing smoke-filled air into the air intake down through the air passageway and out through the exhaust aperture with at least one of the ashtray filter and the motor filter being located within the air flow to remove smoke and impurities therefrom.
