I read how you found that zappicators had no effect on nasties in water, and I'm curious: Have you ever done the same test to see if plasma tube Rife machines (TrueRife, Resonant Light, etc.) kill off the nasties? I'm tempted by the convenience of being able to sleep with a PERL-M in the room instead of being tied down to a zapper for 90+ minutes a day. But, that's a lot of money to spend for convenience, and it would be a complete waste of money if it didn't work as effectively as the Parazapper MY.
