Pinging Kartographer to weigh in.
I have my own well ,we use a Berkey filter
Go to www.internetprepper.com for a ceramic water filter kit that you put together yourself using their filters and two 5 gallon white food grade buckets that you can buy at lowes. Total price including buckets approximately $50.00.
We have assembled and given 4 of these filter systems to our family and friends. This is a good filter for people who cannot afford the $230 Big Berkey. We have a Berkey but are also keeping one of the ceramic water filters as a backup.
