What do you want to filter out?

Basically, I would like to have the same quality (or better) drinking water than if I was using poland spring bottled water.

We've had the Everpure filter (under sink) for 28 years, works great! Use it for all our coffee, tea, and drinking water. Our fridge ice maker is also taped into it via 1/4" copper tubing.

Easy filter replacement once a year, different filters available, (on line or at local plumbing supplies) for different specific filtering needs.

Where you end up depends on where you start. No one who hasn't seen your water analysis can give you meaningful advice.

Thank you. Stating the obvious, I suppose a water analysis is the place to start...
