Personal Ionic Air Purifier

Your first line of inhalation defense against virus, bacteria, mold,allergens, smoke and other harmful airborne particles.


WEIN Mini-mate AS150MM Ionic Personal Air Purifier

The most popular model is the top of the line in personal air purification. Weighing in at a sleek 43g, at 2.5″ x 1.5″ x .85″,  this Air Supply will help to purify your breathing space with the most powerful output that we have available. This unit also comes with a breakaway strap for user safety. Also comes with Solid Platinum Emitter Electroplated Gold Grid. This is the ultimate in advanced plasma discharge design powered by a battery.

More than just a portable ions generator – WEIN air purification technology is designed to reduce and eliminates the airborne threat.

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 odours 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!

US Patent 5,814,135 Portable personal corona discharge device for the destruction of airborne microbes and chemical toxins


Besides good food and shopping, Hong Kong is also known for its air quality and SARS Corona Virus outbreak episode during 2003. 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. Again in the outbreak of MERS Corona Virus in Middle east in 2012 period, WEIN personal air purifier is one of the “must-have” protection many.

Not for use by the infant, elderly, children under 4 years old, pacemaker patients without advice from a medical doctor.


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. While WEIN personal air purifier purified your breathing air space, it does not guarantee 100% elimination of viruses or harmful particles. Use additional precautions whenever necessary!
