I've solved a similar problem with a sand filter (centrifugal separator
)and 2 whole house filters in series. I used just the sand filter for
quite a while, but the final filtering made the water clear as the
finer stuff was still making it through. I tried the better filters in
the whole house units, but it made it a little too clean, lacking any
character at all, besides the filters only lasted a month. I've settled
on the string filters, as a nice compromise.
