How can I tell if my AirTamer® is working?

AirTamer® emits healthy negative ions from the ion emitter brush (i.e. the black brush located on top of the unit). If you put the ion emitter brush close to your lips your will be able to feel the ions tickle your lips. This is because the AirTamer® emits over 2 million negative ions per cubic centimeter every second – this is the highest cleaning power of any personal air purifier in the world!

Additionally, there is an LED on the back of the unit that flashes when AirTamer® is emitting ions.
