From my experience with these types of devices, this one does not work.
I've had experience with actual negative ion generators, and this one does not work at all.<br /><br />It does not create a soft sizzling noise and create a soft flow of air from the graphite bristles.<br /><br />Although the bristles do seem to be referenced to the mains voltage, the circuitry does not produce sufficient stepped-up voltage in order to produce the negative ion generation.<br /><br />===============<br />Updated review:<br /><br />After taking this device apart, I found that it is just a 120VAC to 5V-DC power supply for LEDs.  One of the 5V outputs (in the picture marked "LED102" on the circuit board) is connected to the potted supposed high voltage multiplier circuits.<br /><br />I de-potted the supposed high voltage multiplier circuit, and the circuit board is not populated with any electronic components like it should be (see first photo showing locations for some kind of component, but none have been installed).  Additionally, the circuit board is just a straight through connection to the carbon fiber emitters (see the picture of the blue side of the circuit board with traces that go straight from the 5V input to the carbon fiber emitters).<br /><br />This device is complete BS.  The carbon fiber emitters are not fed with high voltage low amperage power.  It is just supplying 5V to the carbon fiber emitters.  There is no ionization taking place at that low of a voltage.<br /><br />Total rip-off.
