Duster, I saw your name in Pixel's post below and mixed up where to place mine in response.

Thanks bartc I'll search out the right kitty litter in the next two days and try it on my third filter.

I don't think that Silica Gel kitty litter is piezoelectric.Sure, it's made from Silica (silicon dioxide) and I am guessing the logic goes : Quartz is silica. Quartz is piezoelectric. Silica Gel is also Silica, thus it's piezoelectric.
The problem with this is that the Quartz is piezoelectric because of it's crystal structure. Many crystals are piezoelectric, including sugar.
But silica gel does not have a crystalline structure. It's a dried up gel basically.
From Wikipedia:
The piezoelectric effect is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials with no inversion symmetry.

Hi beautox and bartc, rather than search out the right Kitty Litter I instead stuffed some rope caulk and tourmaline crystal in the two ac filters I've built so far and and am satisfied with that. Now back to the music. And thanks to all of you.

The stuff I read about and bought is crystaline. It does no harm anyway.
