Cumulative Global Shipments of nanoe™ Devices Exceed 100 Million Units

The banner in the photo reads, "Celebrating the milestone of 100 million units shipped."

Osaka, Japan – Panasonic Corporation (hereinafter “Panasonic”) announced that the total shipment of nanoe™^*1 devices manufactured and sold by the company in Japan and overseas markets has exceeded 100 million units^*2.

In the 1990s, air pollution became an issue in living environments. In response, nanoe™ originated in 1997 when Matsushita Electric Works, Ltd. (at the time) began research and development focused on purifying the air in living environments, utilising water's properties to dissolve odour components. In 2001, with the cooperation of Dr. Kikuo Okuyama (currently Professor Emeritus at Hiroshima University), full-scale technological development began. This gave birth to nanoe™, nano-sized particulate ions contained in water, generated by applying high voltage to moisture.

Following the completion of a nanoe™ device, in 2003, Matsushita Electric Works launched the world's first nanoe™-equipped air purifier “Air Refresh”. In 2005, Panasonic launched the nanoe™-equipped hair dryer, ionity nanocare Windpress, highlighting the features of nanoe™, which has more than 1,000 times the moisture content compared to negative ions and a long lifespan. Since then, nanoe™ devices have continued to evolve according to their applications and effects, and the range of products incorporating them has expanded. These products include white goods such as residential air conditioners, refrigerators, and washing machines equipped with nanoe™ devices to increase the amount of Hydroxyl (OH) radicals generated, as well as beauty and grooming appliances such as hair dryers and facial steamers equipped with nanoe™ devices to increase the amount of moisture generated.

In addition, against the backdrop of the recent growing global demand for improved air quality, annual shipments of nanoe™ devices exceeded 10 million units in the fiscal year ending in March 2022. Currently, nanoe™ devices are used not only in Panasonic products, but also in facilities and public spaces around the world, including Japanese domestic railroads (16 companies), Japanese domestic and foreign automobiles (115 car models from 9 companies), schools, hospitals, hotels, offices, and commercial facilities, with expansion to 107 countries worldwide^*3.

Panasonic will continue to explore and advance the possibilities of nanoe™ technology to provide clean and comfortable spaces in various aspects of people's lives and society, such as in the field of home appliances, mobility, housing, facilities, and public spaces, thereby helping every individual become the person they want to be.

[History of nanoe™ (partial)]

*1: nanoe™ ions spread over a wide area as they have approximately six times* the lifespan of ordinary ions. Their moisture content is more than about 1,000 times** (by volume) that of air ions, and they are gentle on skin and hair because they are weakly acidic.

* Comparison with air ions: Lifetime of general air ions: Several tens of seconds to 100 seconds, Lifetime of nanoe™: Approximately 600 seconds (surveyed by Panasonic)
** Based on a comparison between general air ions (typical particle size: 1.3 nm) and nanoe™ (typical particle size: 13 nm)

*2: Cumulative global shipments of nanoe™ and nanoe™ X devices from September 2003 to July 2024
*3: As of August 2, 2024
*4: Comparison between the nanoe™ device (480 billion OH radicals/second) and the nanoe™ X device (4.8 trillion OH radicals/second). The amount of hydroxyl radicals immediately after being produced by the generator was measured using the ESR method (surveyed by Panasonic)
*5: Comparison between the nanoe™ device (480 billion OH radicals/second) and the nanoe™ X device (9.6 trillion OH radicals/second). The amount of hydroxyl radicals immediately after being produced by the generator was measured using the ESR method (surveyed by Panasonic)
*6: Comparison between nanoe™ and highly penetrating nanoe™ (Panasonic data)
*7: Comparison between the nanoe™ device (480 billion OH radicals/second) and the new nanoe™ X device (48 trillion OH radicals/second). The amount of hydroxyl radicals immediately after being produced by the generator was measured using the ESR method (surveyed by Panasonic)
*8: Comparison between conventional highly penetrating nanoe™ and 2nd generation highly penetrating nanoe™ (surveyed by Panasonic)
