Bleeker,
For me, a HPF was a bit of a misnomer. A filter, by nature, removes something. So, if it removes the low frequencies, it is a low cut filter. But for some reason it is called a high pass filter. I had to learn to live with this or it would make me nuts.

On your car: air filter, fuel filter, oil filter.
In your house: water filter, air filter
on TB Classified/ebay/CL/etc.: keyword filter
In commercial/utility radio telecom a 2.5MHZ filter filters out everything that is outside a certain minimally adjustable bandwidth centered at 2.5MHZ
All of these filter out everything but what their name suggests they’re supposed to allow to pass through. By the convention of the vast majority of filter nomenclature, the word “Pass” shouldn’t even be necessary in High Pass Filter.
