I was looking at a Whirlpool Central Water Filtration System. This is a self flushing system; therefore, never requires filter replacement. This filter contains a "special grade charcoal," which means activated charcoal. (I think.) Whirlpool sez this stuff should last appx. 10 years.. I understand this stuff is expensive and also understand that Whirlpool may be spreading some B.S.... The bottom line is: One a scale of 1 -10, where does this rate..

AND..Does someone out there have a recommendation regarding a good whole house filtration system.

Our Cities water comes from wells. They do filter it, but not that well....
