: Hi there.

: My impression of these ionizers is that they are simply a device which
: creates a small constant (more-or-less) spark which creates ozone which
: ultimately helps neutralize the slightly charged dust particles so that
: they are not attracted to our boats. Add a small fan for circulation,
: maybe a paper filter just to get the big stuff out of the air, and that's
: it.

: How's it look to you; have you had the cover off it yet?

Pete,
I took it apart when I bought it to clean per the instructions and it has 3 filters. 1 foam pre filter, then the ionizer grid consisting of several layers, then an activated charcoal filter. I removed the ionizer grid for cleaning which is done by soaking in dishwasher detergent or by placing in the dishwasher itself for 1/2 hour. I couldn't believe the sink water after cleaning. It was filthy black! Best I can tell you about it.
