Inhibitory effect on the novel coronavirus
(SARS-CoV-2) by Panasonic’s air conditioner with nanoe™ X

Panasonic Singapore is pleased to announce that global contract research organization Texcell*1 has verified that a Panasonic air conditioner unit with nanoe™ X technology has inhibitory effect on the novel coronavirus (SARS-CoV-2).

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 bacteria and viruses. They are characterised by being strongly oxidative and highly reactive. 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, Panasonic in collaboration with Texcell verified the inhibitory effect of nanoe™ X technology on the novel coronavirus in a small test space of 45L. In the current collaboration with Texcell, Panasonic tested the efficacy of nanoe™ X technology with an air conditioner in a larger test space. The results show that nanoe™ X has an inhibitory effect of 91.4% on the novel coronavirus in a space area of 6.7m3 in 8 hours. This test was carried out in a closed laboratory environment and not in uncontrolled living spaces.

Panasonic has been researching on nanoe™ 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.

For reference:
Testing the inhibitory effect of air conditioner with nanoe™ X on the novel coronavirus (SARS-CoV-2) in a space of 6.7m3. 

• Overview
A comparative verification was conducted in a space of 6.7m3 containing the novel coronavirus. (SARS-CoV-2)

• Results
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


 The air conditioner with nanoe™ X is installed in a space of 6.7m3.
 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.
 The virus infectious titre was measured and used to calculate the inhibition rate.
