This "water filter comparison" website is misleading. While it does contain some interesting information, when you visit the comparison page, you'll notice that Aquasana is top-rated in both the Under Counter and Counter Top categories. When you click on the Aquasana link, you go to a nice-looking order page. Click on any of the other links and you're taken to Amazon. This does not appear to be an "unbiased" comparison, so be warned!
