I answered this before (early December), as quoted below.
Maybe you didn’t see it?
Or maybe you want some other options?
Anyway, here is what we do:

You really need a separate whole house filter, drinking water filter, and 
shower filter.  That way, your drinking water and shower water are actually 
double filtered.  These are the ones we use and they are terrific, especially 
the drinking water filter:
