Dr. Air Vital Air Purifier

Received as a gift at an event.

Brand new and unused.

*   Utilizes the power of negative ions and low-concentration ozone to decompose and suppress invisible viruses, house dust, and unpleasant odors and bacteria in your living space.
*   Goes beyond simply removing dust and pollen; it generates negative ions, abundant in natural environments like clear forests, to create a healthy and relaxing atmosphere.
*   Operates silently as it does not use fans or motors.
*   **Two Mode Settings:** Switch between Normal Mode (for rooms 6-10 tatami mats) and Economy Mode (for rooms under 5 tatami mats) depending on your room size.
*   **Removal of Airborne Viruses:** Experimental results show 96% suppression in 5 minutes and 99.9% in 15 minutes.
    (*Measured in a 200? test chamber before and after operation.)
*   **Removal of Mold Spores:** 99.9% removed in 1 hour.
    (*Measured in a 200? test chamber before and after operation.)
*   **Deodorizing Performance:** Compared to natural decay, methyl mercaptan is reduced to 0% in 30 minutes, hydrogen sulfide to 46% in 30 minutes and 16% in 60 minutes, and ammonia to 88% in 30 minutes and 70% in 60 minutes.
    (*Measured individually using detector tubes in a 27? acrylic container for methyl mercaptan, hydrogen sulfide, and ammonia.)
*   **Electricity Cost:** Approximately 3.3 yen per day and 99 yen per month even when left on 24 hours a day.
    (*Calculated based on a general consumer electricity rate of 27 yen/kWh.)
*   **Economical:** Maintenance involves simply wiping the electrodes and dust collection plate. No need to purchase replacement filters, saving you time and money. It also generates low-concentration ozone using electricity without the use of chemicals, making it economical.
*   **Lightweight:** Compact and stylish design fits anywhere (approx. 20cm width, 10cm height, 10cm depth).
    Palm-sized for portability, weighing approximately 500g (about the weight of 2 apples).
*   **Virtually Silent:** Generates negative ions using discharge technology from asteroid exploration probes, resulting in near-silent operation. Ideal for bedrooms and children's study rooms.

As I am an amateur, please no claims or returns.
