This convenient ashtray uses a small battery-powered motor to reduce smoke and odors from cigarettes, etc. It's an imported appliance that helps prevent passive smoking. The filter is removable, so it's easy to wash. Uses 2 AA batteries. The instructions are in English, but I think they are easy to understand. Operation has been confirmed.
