RO doesn't catch everything, and are kind of a maintenance hassle. You need to be religious about changing the filters, back-flushing, etc. In the end, I decided it wasn't worth the hassle. We have a counter-top water distiller. It does 1 gallon at a time. Over the years, I've gone through 4 of these machines, I think. But I do trust the resulting water.
