While there are many methods available to a photographer to clean the image sensor filter, only the FireFly provides a convenient, safe, and effective method to neutralize electrostatic charges on components of the mirror box, shutter chamber, and image sensor filter, clearing them of undesirable stuff without contact.
The FireFly utilizes a nine-volt battery, and safely multiplies the battery's voltage to a point where corona discharge will occur. The corona discharge field "ionizes" the air passing through the body of the FireFly. Only the FireFly producing and delivering both positive (+) and negative (-) air ions to the outlet air stream. This assures that static charges on the surfaces of the mirror box, shutter chamber, and image sensor filter are neutralized, allowing dust and other particulate matter to be blown off by the air stream delivered at the outlet nozzle.
