Lets try to keep this thread on topic. Negatives: 1) Low CFM 2) essentially no ability to resist back pressure 3) grime (black wall effect) 4) need for and noise (whine) of a separate HV power supply 5) oxidation (corrosion) 6) static charges 7) Negative health effects of ozone byproduct 8) RFI nois...

Consumer Reports in May 2005 tested ionizing air cleaners for ozone levels. Some failed the industry standard sealed-room test for ozone levels by producing more than 50 parts per billion (ppb) of ozone near the machine. Some emitted 150 to 300 ppb of ozone, near the machine. While readings were far...

Preyx is correct, it does produce ozone which would oxidize many materials very quickly and aggressively compared to typical air. It definitely is not good for electronics. The grime turned out to be the first problem. Anything that was grounded tended to accumulate grime. Static charges were not mu...

So this reply has continuity I will talk about a single pin. You would be surprised at how much air a single pin can move. I have Jim Lee's plasma-tron 1000 circa 1990 which has two pins. You can put your hand up to it and feel the breeze. This is long before Lee sold rights to Sharper Image. But th...
