I can't imagine going without my reverse osmosis water filter. (I got
mine at Costco). The improved taste of the water is a benefit of
course, but the BEST thing about it is that it filters out that
lime/calcium/whatever sediment that used to settle in my potted plants
and in my coffee-maker.
I have been using the same coffee-maker for 7 YEARS, and I have
*never* had to clean it with vinegar, not once. I have the filter
changed once a year, and the cost is less than having bottled water
delivered.
