Anyone add a water filter system to their Interstate?
Today's RVtravel.com had a good article on the issues surrounding water filtration: RV Daily Tips Issue 641. June 15, 2015 | RV Travel
Has anyone found a good location to add water filtration to their Interstate? I often wonder what is getting into my fresh water tank (and into me, too.)
The see-through housing Pentek units look good - anyone actually install such a unit with good success?

I don't have an Interstate, but the EVERPURE system I had in another TT didn't take up much under sink room. Read up on it is the recommendation. Airplanes, etc, don't have much room either.

Here is the one we have used with good success. Reasonable price.
Camco Water Filter with Hose - Walmart.com

I use an external granular activated carbon (GAC) filter, that I put right at the spigot on the service pedestal. That way the water is filtered before it even enters my hose, whether I hook up to municipal water or fill the fresh tank.

I use the same as Protag. And for any drinking water we use that's not boiled (e.g. for cleaning teeth) we use bottled water.

To decide what filtration to use, how to do filtration, etc., you need to start with what are you trying to filter? Carbon filters address taste and odor, usually from chlorine, which will mess up your coffee, and give a poor (not harmful) taste to your drinking water.
If you're worried about sediment and silt in your water tank, you would use a sediment filter.
I'm not sure why we would ever need a sediment filter for an RV because by definition we're talking city water to fill our tanks right? whether we get it at home or on the road or in the campground? I read that even city water systems can contain sediment/silt, but I don't think it would be in the amount necessary to cause problems in our systems. If I am wrong, or if you would feel better having a sediment filter, use it BEFORE the water goes into your RV, i.e. somewhere between the water spigot / hose / RV connection.
So that leads me back to carbon. I think the kind of in-line hose filter that Protag is talking about works fine. I bought one when we got the RV, but I have never actually used it. That's because a Brita-type pitcher does the exact same thing, i.e. carbon filter. So we just use Brita-filtered water for coffee. I don't mind brushing my teeth, cooking in heated water, and taking showers in un-carbon-filtered city water which has slightly too much chlorine in it.

Given that… - Camp grounds often draw their "city" water from wells and even though most states require regular testing of well water for contaiminates there is a finite chance for contamination
- The mineral content of even the best "city" water in different localities can result in a bout of Tourista
We have chosen to take the same route as Protag. We use a carbon and particulate filter at the post to trap the odors, sand, dirt and other gross contaminates out of the Interstate's system entirely and we generally use that water for washing and cooking (Cooking water is generally heated to high enough temperature for a long enough period of time to be safe.) For drinking, including coffee and tea, we rely bottled water. A case of Tourista is a bad thing to have on a trip even if you do have a toilet handy in the coach.

Having dealt with filters inside two AS trailers I would be opting for the external filter at the outside water supply. Winterizing with an installed filter is a pain and messy. Dripping water is one thing but spills of antifreeze is quite another. We will be purchasing a filter to mount in the supply hose next time.

Remember with any filter to drain it when you do your winter water drain and line clearing - if it's going to freeze where your AS is stored.
I installed an under sink double filter that worked great.
When the winter came I drained and blew out my water lines - forgot the water filter. Living in the mountains, it froze and ruptured the plastic filter housing and filters. $200.00 lesson!
