Reverse osmosis water is about as good as it gets. Our Spectra has a strainer, a 50 micron filter, a charcoal filter, a twenty micron filter, a five micron filter and then a sub micron reverse osmosis membrane. We typically see 22 ppm on the water tester. Unfortunately the water then sits in our new fiberglass tanks where it quickly gains a certain fiberglass funk which you can smell and taste.
I am glad we have fiberglass tanks and I think that good fiberglass tanks are better than any other possible solution. They don't corrode, they don't conduct, they don't leak, they can be formed to maximize internal volume, they are easy to repair and they last as long as the hull does if done right.
Now what about the skunky water? After doing some research I have come to believe that new fiberglass tanks typically impart a bit of a funkyness to your water but that this wears off over time. We shall see.
In the mean time I installed a charcoal filter under the sink (which required some exotic Euro to US hose splicing). I put it on the cold side only and it has really done the trick. We now drink water out of the cold kitchen tap only.
