I don't know if you're as anal about microbes and chlorine and other unhealthy stuff that your body has to filter out of the crap we drink and eat as I am.
But if you are, you might want to know about a top-rated water filter that I just purchased online after doing some research into that stuff to find the best product for the best price.
It's the Aquasana AQ-4000. Check out THIS CHART that compares the top brands. It takes out virtually every bad thing from the city tap gunk and leaves in the good minerals. It ends up costing less than 10 cents a gallon (beats the hell out of the $1.20 spring water from the grocery store).
I've been using a Brita brand filter for a year and thought it was pretty good (good smelling and took out chlorine and lead but little else), until I saw it compared with other top brands. The Aquasana is actually cheaper over the long run, much cheaper, and takes out all the crap. It's also topped the critics' sites for the last six years on quality and price ($99).
If you want to save your liver the nasty work and get rid of that awful tap-gunk smell and taste, I highly recommend the Aquasana. Mine will be delivered early next week. Can't wait.
