1 Refer to the official test report EIDD-ID Core-2021008-006-002-R from Infectious Disease Core Facility of Academia Sinica (Taiwan). The test virus is human coronavirus 229E (HCoV-229E; ATCC VR-740).
2 Refer to the official test report 2020_0031 from Japan Kitasato Research Center for Environmental Science. The test virus is Escherichia coli phage MS2 NBRC 102619.

How does Airvida remove the coronavirus in the air?

A Coronavirus contains capsid, spikes, RNA
Due to RNA is very weak, if breaking a virus’ capsid, this virus will be easily inactivated

Airvida generates over 2 million negative ions around user’s facial area
Airvida’s negative ions will attach on coming airborne virus’ capsids and spikes, then break their capsids

Those negative ions carry ample electrons to break 300~500 million covalent bonds
Those sufficient electrons can disrupt and break virus’ carbon-hydrogen bond and make them inactivated immediately
According to a study by the University of Cincinnati, the penetration rate of the virus to a surgical mask is 21~85%.
Airvida wearable air purifier enhances protection and reduces the inhalation of more than 99.7% of coronavirus, reducing the suspension of viruses near the nose and mouth.

Do you know?
Long-term exposure to a polluted environment will increase the mortality rate of COVID-19.
An increase of 1 microgram per cubic meter of PM2.5 will increase the fatality rate of patients with the new coronavirus by 15%.

How does Airvida purify the pollutants in the air?

Airborne particles including
PM2.5, PM10, pollen,
formaldehyde, secondhand smoke, pet dander

Airvida generates negative ions
Airvida generates 2 million negative ions every 0.6 seconds around the user’s facial area

Negative ions will attach the particles within close proximity
Turning them into bigger & heavier chunks and thus falling to the ground
