Generating ozone and negative ions in the air can be done by a corona discharge. For this we can use a sharp tip of negative polarity, acting against a flat metal part of positive or neutral potential ...

[Advanced Tinkering] needed a source of fresh ozone for some future chemistry related projects, and since buying an off-the-shelf unit would be, well, just plain boring, it was obvious what to do ...

The design of the circuit is aimed to produce a device that would remove microscopic particles from the air instead of using fans and filters, by generating negative ions or ionizing the air. Ion – an ...
