In commercial frequency ionizers, the frequency for generating ions is a low
50/60 Hz
that results in
a poor ion balance over short periods of time. This causes ions within the tube to be extinguished,
making carrying ions through the tube impossible. The Koganei ionizer, on the other hand, uses a
high frequency of
68000 Hz
to achieve an excellent ion balance that avoids ion neutralization within
the tube, thereby enabling ions to be carried through the tube.
