Ionic Mist/fog makers

[Brandon]

This may be off topic, but I cant think of a better group to at least find a
lead.

I am speaking of these new Ionic mist machines that are being sold. Glass
bowl filled with water uses an electric oscillator of some sort to produce a
cool fog like mist. They also claim that these units produce negatively
charged ions and help clean the air, any truth to this?

I am curious as to how the device works, how simple it is, and if it would
be possible to make one, perhaps on a larger scale in order to produce
larger volumes of mist/fog. The application would be for high humidly
greenhouses/grow rooms( no I am not growing pot) or as a cool mist
humidifier in a home.

Thanks

A drawback to the ultrasonic device you describe is that not just the
water but everything in it gets sent into the air. Use hard water and
you end up with mineral dust all over the place pretty quickly. Using
DI water is the only way around it.

So you mean that distilled water is the way to go...?

De-ionized (DI) water if you can get it free. If not, distilled is
fine.
You want as close to zero dissolved solids in your source water as
possible.
In a home, mineral dust gets on - and into - into everything ... CD
players, computers, and all other places you don't want it. In your
application, greenhouse, you don't want your plants' leaves to be coated
with mineral dust. Right?
