I was kinda hoping this was a truly standard module that I could recommend for building DIY ionisers, but now I'm aware that there are other variants with the same name. These modules are suitable for other applications requiring high voltage DC at very low current. But the high voltage should always be regarded as being referenced to mains voltage.

The universal 110-220V voltage is really just fixed value resistors that get hotter when used with higher voltages. No problem, since we can stick a couple of sleeved quarter watt 18K resistors in series to help spread the dissipation when using above 200V.

The output voltage of these units is actually quite zesty compared to a classic ioniser, meaning they will potentially generate more charge in the air.

The principle of operation of an ioniser is that when a high DC voltage is applied to a sharp point it causes the air to take on a charge with respect to ground. That causes charged particles in the air to precipitate to surfaces in the room or makes them stick to filters in air cleaners.
A very slight electrical plasma (corona) discharge is also created at the ionisation tips, which results in creation of short-lived active air molecules as found in outdoor air, that have a deodorising and sterilising effect on the air as they revert back to stable molecules.

The use of carbon fibres is because they are very sharp and work well as ionisation emitters. Traditionally steel needles were used.

Here's a typical AliExpress listing for what looks like the same module:-

And one of the big spicy-mama ones, which appears to be universal voltage too:-

Here's a video about the big one, with a schematic:-

If buying the modules from eBay the keywords anion module should work.

Be careful about buying 12V modules. Because they create a high electrostatic charge with respect to ground they can stress the insulation or cause flashovers inside standard power supplies. Not a problem on vehicles or off-grid accommodation with 12V and grounded chassis, but if using with isolated supplies the negative on the low voltage side will need grounded.
