Decided after much research and trial and error. GE FXHTC used to be used but their quality has gone down as GE stopped making them and just sold the rights to the name. SimPure elements are significantly heavier, indicating more carbon and better filtration. They are well packaged and sealed (I assume the charcoal doesn't absorb odors and deposits before use, good idea. The smell of the water is perfect and the sediment doesn't go away. Sometimes there is a small amount of rust in the toilets, but I haven't had any problems so far I usually change them every 6 months (I have city water) and haven't noticed any significant change in faucet pressure or flow during that period.
