Water filter basics and variations

[Raining Star]

It's time to replace all the water filters on my Winnebago Chieftain and the variety of filter types and the range of prices is somewhat bewildering. How much of all these features are meaningful and how many hype?

Also since day one I've always wondered why there isn't some kind of filter on the "city water" intact. Wouldn't this be the obvious place to at least be filtering particles? Does anyone make one?

I bought a GE SmartWater whole hose filter housing and the hose fittings needed from a Home Depot and have used it for 11 years. Cost for the housing was about $20. All the incoming water goes through it. The filter cartridges go for from two for $9 or so to two for $13 or so. The more expensive ones are charcoal taste/chemical with some sediment filtering. The cheaper ones are strictly sediment filters. In some areas I use a Flopur Mark 8000 water softener after the filter. I use quick disconnects on everything.
