Panasonic today announced that, in a European first, Texcell*1, a global contract research organisation, has certified the inhibitory effect on the novel coronavirus (SARS-CoV-2) by an air conditioner with nanoe™ X. Texcell verified 91.4% of the inhibitory effect on the novel coronavirus in a space of 6.7m3 over 8 hours.
nanoe™ X is a 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 certain bacteria and viruses. They are characterised by being strongly oxidative and highly reactive, hence a short life span. Contained in tiny water particles, nanoe™ X has a long lifespan and can spread over long distances. It has an inhibitory effect on both airborne and adhered substances.
In September 2020, and in collaboration with Texcell*1, Panasonic verified 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. For further investigation, Panasonic challenged to test using an air conditioner with nanoe™ X in a larger test space. Even in these difficult circumstances, Texcell has now certified that the nanoe™ X does have a 91.4% inhibitory effect on the novel coronavirus in the actual space of 6.7m3 over 8 hours using the air conditioner with nanoe™ X. This testing was carried out in a closed laboratory environment and was not designed to assess its efficacy in uncontrolled living spaces.
Panasonic has been conducting research on nanoeTM 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*2.
Panasonic will continue to pursue the potential of nanoe™ X technology to address possible risks associated with air pollution such as new pathogenic microorganisms, to create healthy environments for people around the world.
Testing the inhibitory effect of air conditioner with nanoe™ X on the novel coronavirus (SARS-CoV-2) in a space of 6.7m3.
A comparative verification was conducted in a space of 6.7m3 containing the novel coronavirus. (SARS-CoV-2)
Over 91% of novel coronavirus (SARS-CoV-2) activity was inhibited within 8 hours.
Note: This verification was designed to generate basic research data on the effects of nanoe™ X on the novel coronavirus in laboratory conditions different from those found in living spaces.
・ Methodology and data
Organisation ：Texcell (France)
Subject ：Novel coronavirus (SARS-CoV-2）
Device ：Air conditioner with nanoe™ X (Etherea model CS-Z25VKEW)
Ø The Etherea air conditioner with nanoe™ X is installed in a space of 6.7m3.
Ø Gauze saturated with SARS-CoV-2 virus solution was exposed to an air conditioner with nanoe™ X from a distance of 0.7m in a 6.7m3 room for 24 hours.
Ø The virus infectious titre was measured and used to calculate the inhibition rate.
・ Test result
|Test Subject||Inhibition rate||Capacity||Hours|
|SARS-CoV-2||42.4%||6.7 m3||4 hours|
|SARS-CoV-2||91.4%||6.7 m3||8 hours|
|SARS-CoV-2||99.7%||6.7 m3||24 hours|
