Are these really necessary? I'm told they are because the condensate is a high ph and will melt my drain pipes (pvc).

Condensate is typically a Low ph, referred to as acidic.
Acidic water can leach metals from pipes and fixtures, such as copper, lead and zinc. It can also damage metal pipes and cause aesthetic problems, such as a metallic or sour taste, laundry staining or blue-green stains in sinks and drains.

I don't think there is such a thing as a "condensate filter".
There are condensate neutralizers, which have inside, calcium carbonate/ marble rocks, which neutralize the acidic condensate from gas burning condensing appliances.
The neutralizers are sized based on equipment specifics.
I have seen a few idiotic, non-professional installations where condensate was run into copper pipes and those pipes developed holes (of course!)
