Aromatherapy Functionality

The ZQA-4000B Air Purifier features a thoughtful aromatherapy function, allowing you to add your favorite essential oils to seamlessly blend refreshing scents with powerful purification. While thoroughly eliminating odors and purifying the air, the naturally diffused pleasant fragrance further enhances indoor air quality, helping to soothe emotions and create a tranquil, relaxing atmosphere—making every breath a true delight.

Convenient Timing

Whether it's quickly purifying cooking fumes, continuously refreshing the air during work hours, operating quietly for better sleep, or even presetting before leaving home—all can be accomplished with a single touch via flexible timer modes. Offering 2/4/8-hour multi-stage timers, you can freely set the duration. The unit automatically shuts off at the preset time without manual intervention, saving energy and making operation effortless.

Smart Filter Replacement Reminder

When the filter cartridge reaches the critical usage threshold of 2000 hours, the filter replacement button will activate a red alert to prompt you to replace the cartridge promptly. After replacing the filter, press and hold the filter replacement button to reset the usage timer. (Important: Before replacing the filter, always disconnect the power supply to ensure safe operation.)

With a light touch of your fingertip, effortlessly switch between modes—Daily Clean, Rapid Odor Removal, and Sleep Mode with Low Noise—each providing the perfect airflow for every lifestyle scenario. Truly achieving “air at your command,” it seamlessly combines purification efficiency with a comfortable experience.
