How it works

Air Supply generates an intense electrostatic ion wind that charges floating particles in the breathing zone. The particles are then repelled away from the wearer substantially creating a particle free exclusion zone for toxic allergens, smoke, dust, viruses and bacteria in the breathing zone. Perfumes and odors are also minimized by the Air Supply ionization effect.

Significant and substantial reductions of airborne breathable particles have been confirmed by leading world authorities in health related aerosol studies by WEIN Air Supply technology from 0.04 to 3 microns in size. This represents most viruses and bacteria. Because this happens outside the body, it does not matter how infectious or toxic these particles are!

Substantial inhalation risk reductions were confirmed under strict laboratory conditions in confined spaces (aircraft cabin simulations) and large test calibration chambers (rooms) used.

A leading aerosol scientist who peer reviewed the studies said:

“Whether a particle is biological or virulent in humans is of no relevance while it is airborne. While still airborne, these virulent particles obey the same laws and effects as all airborne particles of the same aerodynamic size and density.” 

Testing with inert particles of the same size and density therefore yields a very powerful methodology to characterized any  floating particle whether infectious or not!

Beside good food and shopping, Hong Kong is also known for its air quality and SARS episode during 1993. Hong Kong people know best when come to protecting themselves from hazardous air pollution. Over the years, many Hong Kong celebrities, businessmen were seen carrying WEIN Air Supply personal air purifier at different occasions to better protect themselves from airborne pollutants, viruses and bacteria. These are not from commercial product endorsement events.

These ionic devices are not medical products! Do not reduce or eliminate any approved therapy or drugs prescribed by a physician. These do not treat or cure any disease of the body, but they do reduce the inhalation risk of airborne viruses or bacteria similar to the action of a mask.
