China’s “secret weapon” appears on the list again
In view of the current mutation of the new coronavirus, the continuous emergence of new variants of viruses such as Omicron and has attracted widespread global attention. and strong concerns, the World Health Organization (WHO) responded quickly and held a special seminar on December 17, 2021, introducing and recommending the important functions and roles of new ultraviolet technology-"222 nanowave" in epidemic prevention. During the live broadcast, experts from the World Health Organization introduced the characteristics and experience of nanowave technology, and thanked and recommended the world's leading organizations and companies in this field. The reporter was pleasantly surprised to discover the figure of "Lumenlabs" representing Chinese technology. It was the "secret weapon" that participated in ensuring that the Chinese sports delegation had zero infection with the new coronavirus in the Tokyo Olympics a few months ago.

In the live broadcast of the conference, Professor Ed Nardell of Harvard Medical School first made a speech. He believes that cases of infection in indoor environments show that rapid air disinfection must be carried out directly in the indoor space, rather than indirectly through the ventilation system.
He introduced a mass infection incident that occurred in a primary school between May and June 2021. The incident was infected by a teacher who carried the Delta coronavirus (not vaccinated). Although all students in the classroom wore masks, the classroom was well ventilated, and even a HEPA air purification system was used, 50% of the students were still infected.
(Professor Ed Nardell compared several methods of real-time indoor disinfection)
Professor Ed Nardell introduced at the meeting: "If air ventilation is used to reduce airborne diseases, the US CDC recommends 6-12 air exchanges per hour." He summarized and compared several commonly used methods:
1. Natural ventilation such as opening windows and doors is not advisable, because this method depends on room design, outdoor weather and other conditions.
2. Ventilation through the fresh air system is very expensive and the air flow is limited.
3, the 222 nanometer wave of the new far ultraviolet technology is used to disinfect the whole house, which is currently the most direct and possibly the most effective disinfection method.
(Professor Ed Nardell introduced the human safety experiment)
Professor Ed Nardell introduced that in the upper air sterilization, when directly disinfecting about 20% of the air, the air mobility is required to be high. The 222 nanometer wave can directly disinfect almost all the air, and the air mobility is low. Moreover, the economic performance of the generation and use of 222 nanometer waves is much higher than other disinfection methods. More importantly, 222 nanometer waves will not be absorbed by the human eye and the outermost layer of skin, cannot penetrate human tissue, and are very safe. Moreover, the outermost cells of the human body are constantly metabolizing, so even long-term exposure to 222 nanometer waves will not have adverse effects. If 222 nanometer waves can be used reasonably for air disinfection, it is unlikely to cause any serious medical consequences to the user.
(Dr. Kenneth Wood introduced the effectiveness experiment of 222 nanometer waves)
Regarding the prospects of 222 nanometer waves, Dr. Kenneth Wood from the University of St. Andrews in the UK and Dr. Ewan Eadie from the School of Medicine and Ninewells Hospital of the University of Dundee in the UK made special introductions one after another.
Dr. Kenneth Wood believes that hundreds of millions of people are hospitalized every year due to bacterial or viral infections. 222 nanometer waves may be able to improve this situation, especially during the epidemic. This technology should be fully used around the world. He said that if there is a virus or virus carrier in a 30 cubic meter space, 222 nanometer waves can quickly reduce the virus and achieve a 92% elimination rate. Experiments have shown that the disinfecting effect of 222 nanometer waves on the new coronavirus and influenza virus is better than that on bacteria. ACGIH's new threshold standard During the experiment of 222 nanometer waves, the data showed that the effect of 222 nanometer waves in the experimental space (30 cubic meters) is equivalent to 3,000 air exchanges per hour ((3,000 ACH, which is equivalent to 25,000 liters of air change per second in this experiment)), which is much higher than the US CDC standard (6-12 ACH air changes per hour).

In addition, the 222 nanometer wave disinfecting method has no human factors and is more reliable than opening windows for ventilation, maintaining social distance, wearing masks, getting vaccines , etc. In reality, any disinfecting method that relies on human behavior is unreliable in the long term.

Ewan Dr. Eadie then shared the safety experiment of 222 nanometer waves. He said: 222 nanometer waves cannot penetrate epidermal cells, and the penetration rate is less than 0.1%. In the experiment, assuming that the UV index of sunlight is 4.1, the damage value caused to the basal layer cells of the skin for 10 consecutive minutes is equal to the damage value caused to the basal layer by the 222 nanometer wave generator for 30,000 hours of continuous operation.
In addition, 150 TLVs of 222 nanometer wave generator irradiation did not cause obvious damage to Langerhans cells in the epidermis, while 1 TLV of traditional ultraviolet lamp irradiation caused obvious cell migration. Therefore, 222nm waves are both effective and safe.
According to reports such as the London Post in the UK, UL in the United States has updated the safety standards of 222 nanometer waves a few months ago, providing a standard basis for the world's leading "human-machine coexistence" disinfection method, and also starting a global battle for 222 nanometer wave standards. The Japanese media also regards 222 nanometer wave as the trump card to fight against Japan's "sixth wave" of the epidemic. Japan's representative companies of 222 nanometer wave are also gearing up around the world. "Lumenlabs", the "secret weapon" of China's 222-nanometer wave anti-epidemic, has been "disappearing" since it guaranteed zero infection for the Chinese sports delegation at the Tokyo Olympics in Japan. This time it appeared at the World Health Organization's symposium and used the international brand "Lumenlabs". This is also the first time that "Lumenlabs" has returned to the media.
Taking this special meeting of the World Health Organization as a starting point, let us wait and see whether 222 nanometer waves will bring about a revolution in the disinfection industry and bring new opportunities for mankind to eliminate the epidemic. Whether China's 222 nanometer wave standards can compete with the standards of the United States and Japan.
