Is your traveler always complaining about the sniffles, a stuffy nose, or scratchy throat? The AirTamer promises to help allergy-prone passengers enjoy fresh air right from their seat. The personal air purifier emits a stream of negative ions to help force airborne pollutants away like dust and bacteria. The device is silent, about the size of an MP3 player, and uses 2 included lithium coin cell batteries. The electrostatic purification creates a 3-foot sphere of cleaner air.
