Panasonic Vietnam has recently received public feedback on the inhibitory effect on SARS-CoV-2 confirmed by the Panasonic’s air conditioner with nanoe™ X, we would like to clarify as follows.
Nanoe™ X is an electrostatic atomization technology, that collects invisible moisture in the air and applies a high voltage to it to produce “hydroxyl radicals contained in water”. Hydroxyl radicals inhibit the growth of pollutants such as bacteria and viruses. They are characterized by being strongly oxidative and highly reactive, hence a short life span. However, the “hydroxyl radicals contained in water” was verified to have a longer lifespan and disperse across a wider area. Nanoe™ X has an inhibitory effect on both airborne and adhered substances.
Panasonic has been conducting research on this technology over the past 20 years since 1997, and has verified its effectiveness in a variety of areas, including inhibiting pathogenic microorganism (bacteria, fungi, and viruses) and allergens, breaking down PM 2.5 components that have adverse effects on the human body*1.
In 2012, Panasonic conducted a test with a third-party organization and announced that "hydroxyl radicals contained in water" technology could be expected to have an inhibitory effect on new viruses*2.
In September 2020, Panasonic has verified in collaboration with Texcell*3 the inhibitory effect of the nanoe™ X technology with the benefits of hydroxyl radicals on the novel coronavirus in a small test space of 45L using nanoe™ X generator. As the result, over 99.99% of novel coronavirus (SARS-CoV-2) activity was inhibited within 2 hours. The test information was published on Panasonic Vietnam website at: https://www.panasonic.com/vn/corporate/news/articles/20201026-verification-of-inhibitory-effect-of-nanoe-tm-x-technology-with-the-benefits-of-hydroxyl-radicals-on-novel-coronavirus-sars-cov-2.html.
After that, Panasonic continued to cooperate with Texcell to test using air conditioner with nanoe™ X in a larger test space. Even in this circumstance, Texcell has now certified that in the actual space of 6.7m3 the nanoe™ X does have 91.4% of the inhibitory effect on SARS-CoV-2 in 8 hours and 99.7% of the inhibitory effect on the SARS-CoV-2 in 24 hours using the air conditioner with nanoe™ X. The test information was published on Panasonic Vietnam website at: https://www.panasonic.com/vn/corporate/news/articles/20210324-phong-chong-covid-19.html.
As mentioned clearly in individual reports, the tests were carried out in a closed laboratory environment and were not designed to assess its efficacy in uncontrolled living spaces.
