This innovative air purifying ashtray effectively cleans the air while you smoke. Its built-in negative ion filter releases ions to actively adsorb tar and other particles. The unit operates in complete 360-degree silence at only 30dB, ensuring it won't disturb others. Crafted from durable, super-hard ABS flame-retardant material, it safely holds cigarette butts without melting or deforming. Key features include a convenient 20-minute auto-shutoff to save energy, an independent design for easy cleaning, and a compartment for an included aromatherapy tablet, allowing it to double as a pleasant diffuser. Powered by 2 AA batteries (not included), it's perfect for spaces under 10 square meters like car interiors, letting you smoke indoors comfortably. The package includes the ashtray, one cotton filter, one aromatherapy tablet, and a user manual. Please note: Product colors may vary slightly from images due to monitor settings. Slight dimensional variances are possible due to manual measurement.
