I need a 10-15KV supply for an electronic air filter.
Thought I'd pick up a free CRT TV and take the anode supply
out.
What's a typical relationship between CRT size and anode voltage?

There isn't one.

Are you saying that a 5" CRT is likely to have the same high voltage
as a 20" CRT?


Alternative sources for free HV supplies at near zero current would
also be helpful.

Dunno about free but google cockcroft-walton voltage multiplier.

Don't forget the megohms series resistor.

I was surprised I found nothing on ebay.

Thanks, mike
