What is the best non-mechanical water filtration system for home?”
We keep our Britta sitting on the counter and filter our drinking water through it and it works really well. I am allergic to chlorine and get a really upset stomach drinking chlorinate water. The Britta takes care of it. We even take it in the RV with us on vacation, so it has worked in many different municipalities to make the tap water taste good. And it is much less expensive and takes up less space than bottled water. Also, I keep one of these http://www.strangenewproducts.com/2006/10/corn-based-water-bottle-with-filter.html in my car and refill it for running around drinking water. It works great for flying and making that nasty tasting airport water drinkable. And it is compostable when you are done with it.
