[Greenbuilding] Whole house water filters

[Irina Golfman]

Hello,

About a year ago there was a lively discussion about the whole house water 
filters, but for some reason I couldn't find it searching through google. 
We are on city water and are mainly interested in filtering out chlorine 
and it's by-products, fluoride, and sediment the few times a year when they 
flush the hydrants. My water is already alkaline and a bit high on sodium. 
I was recommended a whole house filter made by SpringHouse. It looks great 
but is extremely expensive ($3000). Anyone has any experience with this 
particular filter or suggestions for alternatives to look at?

Thank you very much,
