Trying to track down a UK based manufacturer of mains filtering equipment....
A couple of years ago I came across a fairly small specialist UK based company that offered some reasonably priced solutions for mains cleaning / isolation / filtration, iirc one of them included an external mains rod and some cabling.
For the life of me I now can't remember who they are / what they're called, despite hitting the search engines. It's that age-old problem of not being able to find the thing if you don't know what it's called! :-)
Does anyone have any suggestions?
Thanks,
Steve
