No idea, but they are very simple mechanical, piezoelectric devices that
seem to last forever. It's just a spring that is tensioned and released
by the trigger so it strikes a couple of piezo crystals. The better ones
are easily recognized by the two "barrels" for both positive and
negative charges.
Here's where a guy made his own out of the guts of a gas lighter. At the
bottom is an easy test to see if any ionizer is working. My HiFi version
passed.
