Drinking water filter systems are not created equal by any means. There are standard cartridge filters systems, reverse osmosis systems and specialty cartridge systems like Aquasana. So which one should you look at? A standard cartridge system typically uses a sediment and carbon and/or specialty filter. For most homes using city water, this is actually a great system for such an economical price. Specialty cartridge systems like Aquasana are exactly the same thing except you are forced to use their filter. http://www.isopurewater.com
