We installed this last summer and it works great!
For drinking water on board we use a GE whole house, cartridge style, water filter set up using this cartridge
& this GE housing
. It installs between the output of the pump and the fixtures and is very, very easy to do.
For added filtering we also have a Brita
faucet mounted filter in the galley on the faucet for double filtration. We drink right out of our 1979 tanks with this set up no problem!!
One thing about filters is you need to "exercise" your water system at a minimum weekly or the filters will go bad. I run the water for about a minute each time I'm on board and this keeps the filters fresh. We save a ton on bottled water by being able to drink right out of our tanks and get a full season out of the GE filter.
Location is behind the starboard settee.

Sorry about the insulation in the photos but it kept the boat cool when down south..
