Besides the ones with fans there are also ionizing bars (static bars) still effective around 10cm distance and can cover a whole lp radius. These are silent and one may even use it like a tonearm and put it in position during playback.
There are also photoionizers that use x-rays to ionize gas molecules. These are very effective, can work from farther. I am looking into these.
