Electro-Static Air Filters help with parts and schematic

Hi, I found this schematic how to make Electro-Static Air Filter.

Can anyone help me to outsource the parts from farnell.com, elfa.com online catalogs.

Are caps ceramic or polyester or polypropylene?
What are specs for by711 HV diode amps, voltage etc.

I'm having hard time finding T1, tried searching "trigger coil" to no
avail. Has it any other name, model etc.

This filter claims no ozone and safe design if shorted or touched by hand as it uses NE-2 bulb, are these claims true?

Attached is the datasheet for the BY711 which I found by doing a Google search for "BY711".

I found this tidbit of info on trigger coils after doing a Google search for "6KV Trigger Coil".
