Which water filters?

After reading a number of threads it would appear that putting a filter BEFORE the tank wouldn't be all that great an idea due to possible bacteria build up. So then I'd have to put one after the tank. The freshwater system in by boat does route the transom shore hookup to the tank, just into the stern end of the system. So if I want to filter the galley sink (cold water) and the cockpit ice maker I'll need to add two filters. I can live with that. Finding the right place to install the galley filter will be a bit of a challenge but not impossible. The cockpit location has plenty of room in the engine compartment below.

I'm really only interested in taking out the typical 'hose water' stale taste. The water around here is decent enough otherwise; no sulfur or other strong smells.

So whose water filters should I consider? Which ones aren't worth bothering?
 
Why is it a bad idea to filter all water coming into the boat. We have been doing it for years with a charcoal canister filter mounted on the dock post.
Also have an inline filter for when you are at a different marina. Goes right onto the garden hose.
 
Supposedly the carbon filter removes enough of the chlorine to present a problem with bacterial growth.
 
If you use the water on a regular basis, and replace it as it's used, there shouldn't be any problem whatsoever. A filter before the water comes into the tank should be adequate - lots of people do it that way. Just don't let it sit in the tank for months on end without being used (See, here's a good reason to use the boat as often as possible - gotta keep the water fresh! [:-jump][:-jump])
 
Well, given the fact that the tank can be filled from the bow, but not from the transom shore connection makes it sort of a problem. If I use the gravity fill on the deck there's no real way to filter it. If I connect to the transom connection that won't fill the tank. Now, I am thinking about running a bypass around the fresh water pump to allow manual filling from the transom connection. But even with that there'd still be the issue of no filtering via the bow. I have no desire to deal with stowing an in-line filter that attaches to the hose. There's enough crap aboard already without adding yet something else that has to get moved around.
 
I installed a bacteria/taste filter under my galley sink. The output of the filter has a tee and supplies both the sink cold water AND the icemaker through the 1/8" diameter tubing. I had to snake the small icemaker tubing about 15 feet, but it was really easy since it was so small and flexible. I did not even need to drill any new holes since the tubing fit around other existing lines. Why do you need two filters? I did put a small ball valve in the 1/8" line to isolate the icemaker.

Good Luck,

Tom
 
The icemaker is up in the cockpit, nowhere near the galley. The freshwater system runs along the starboard side of the boat. From the tank under the berth, to the galley sink, head and then back to the transom shore connection. From there a line runs to the cockpit sink (cold only) and the icemaker on the port side. It's be easier to just add a filter to that line only instead of running a whole other line.
