Vinyl static ionizers who's used them?

lewn you are exactly correct. I’ve been in and out of the audio business during my career and have worked for a few big name audio companies.   I’ve seen companies do exactly what you are saying.  Even to the point of buying a cheap ready made product, changing it slightly, putting it in a fancy case and calling it an “Audio” product and charging  10 times what it originally cost.  That’s why after looking at a few things I thought geez, I can make one of these or just buy something ready made cheap.  And yes I did see the devices you mentioned.

Antinn, I haven’t taken the time to look at your references but there are two types of these devices, so far as I can tell. One type works via electrostatic discharge. That’s the type that produces ozone. Humans should not be in the room when they’re operating . The other type is an ion generator which doesn’t create ozone, at least not to an appreciable degree. I believe the devices we’ve been discussing fall into the latter category, save possibly for that plasma lighter. But it would be benign most likely due to its low power, very local effect, and brief period of activation.

@lewm I saw the Acaia release this last week and it seems awesome. I have a big problem with chaff clinging in my Baratza grinder and will be picking up the Ion Beam. I will definitely be trying it with my turntable to see if there's any benefit. Acaia make great products and I own a few of them and highly recommend them. 

There's an obvious effect that the Destat III has in letting a rocket blower remove dust that otherwise won't blow off. I'm not aware of hearing static pops one way or the other, so I do this just my stylus's sake.

There is something unclear to me though, and the Destat III comes with rudimentary instructions. Is there any benefit to repeating it on the second side? I don't think there is, but static electricity is like black magic to me. If I blast one side with (I think) negative ions am I just creating a positive charge on the other side?

Actual science suggests that the static charge between the LP surface and the platter is unaffected by discharging the playing surface and quickly migrates to distribute over both sides, when you flip the LP to play side 2. This suggests you need to discharge both sides, one exposed surface at a time.
