The Mini-Mate Wearable Air Purifier by Wein Products is the ultimate in personal air purification. As the top-selling item in the Wein Products line of advanced and scientifically-acclaimed respiratory protection products, the Mini-Mate has been praised by editors from travel guidebooks Frommers and Fodors, as well as hundreds of research laboratories around the world. Weighing in at only 1.5 ounces, this sleek wearable ionizing air purifier will let you fight back against indoor pollution by creating your very own personal anti-smog zone using the most powerful ionization technology available. Contaminated surfaces and air are sanitized using ionized streams of electrons which destroy the pollutant molecules. An infinitesimal level of activated oxygen (O3) produced in the corona completely neutralizes any residual odor-causing elements in the outgoing pure airstream. The Mini-Mate"s patented emitter and grid are made of pure platinum and solid gold electroplated stainless steel. And, best of all, there are no filters to change. Ready to go whenever you are--to the gym, on the plane, in taxis, crowded elevators or anyplace you need to re-assert your control over your personal air space to create a cleaner, healthier fresh air domain of your very own. The ionization technology used in the Mini-Mate was developed by Wein Products, Inc., a world-renowned innovator in environmental technology since 1964. Working in conjunction with independent scientists from leading universities and research institutes, Wein Products air purifiers are considered the gold standard in air ionization technology by countless scientific and research institutes worldwide that have studied the effectiveness of this technology using their patented products.
