I dug this old ioniser out because I was sure it had a nearly identical PCB to the older version I'd taken apart.
It does, but this one had been in use for some time. When I bought it on ebay as used it was making hissing noises inside but producing no detectable output into the surrounding air.
The PCB is discoloured where tracking has occurred between the high voltage circuitry and the inappropriately close mains ground referenced end of the multiplier.
You can see where the needles have been discharging directly to the adjacent diode leads and there is a strange crusty corrosion on them that has clearly made matters worse.
The hissing noise inside was the high voltage tracking directly across to the low voltage area and rendering the ioniser useless.

can you recommend an ioniser
That could be fixed, right? .. desolder/remove the emitter needles and track.. wire across to copper tape with some isolating insulation — just so long as sufficient separation of voltage multiplier from emitter section can be achieved..
Am I talking rubbish?!
Always fascinates me. That the glow rod erm no don't shove that electrical tesla thing up ones butt. is a Quack thing and outside the USA, Ionizers are considered good items. Inside the USA, generally Quack , not as Quacky as the glow rods but other than the smell of ozone, they never caught on around at least the Midwest were of all the places you'd think it would. (Warm muggy air = mold. X_X yuck although mentioning the word MOLD anywhere will get bad looks from the older generation :O
If you covered the board in a non-conductive resin, would it fix the issue?
why don't you design ,produce and market such a product I am sure you would corner the market in such a product it seems that to get any fresh air in this day and age pure air is valuable commodity.
What Ionizer or purifier would you suggest for hey fever sufferers,
How can 630V caps and 1,000V diodes produce the high voltage without failing?
