AirTamer High-Performance Rechargeable Personal Wearable Air Purifier. The AirTamer A310 is a high performance rechargeable personal air purifier. AirTamers Advanced Ionic Technology emits a constant stream of healthy negative ions that force airborne pollutants away from your personal space giving you a 3 foot sphere of cleaner, healthier air around your head. It cleans the air of atomic sized pollutants (e.g. viruses, pollen, smoke, molds and dust mites) that traditional air purifiers leave behind. It is silent in operation and its extremely energy efficient Power Boost technology provides 150+ hours of run time on one charge. The AirTamer A310 includes an internal lithium battery that is easily charged using the included USB cable. AirTamer's design is ultra-compact and incredibly versatile. A proprietary conductive adjustable lanyard dramatically improves performance and increases run time. You can wear it around your neck (strap included) since it is smaller than most MP3 players
