Didn't want to hijack the water softener thread...
We actually have great water where I am, though our house's plumbing is less awesome.
Moreover, I'm just... funny about water. I have a sodastream and keep limes on hand to get myself to drink the stuff.
Right now we have a Pur filter pitcher, which replaced a Brita. Both of them seem to clog up quicker than I'd like, and worse, if a guest refills it with water that hasn't been left to run cold, it'll plug up instantly.
In the name of convenience and fridge space, we want to add an under-sink filter plumbed to the cold line so we always have filtered water.
What a clusterberkeley researching that has been. I checked Consumer Reports, and whether or not their info is worth a damn, I didn't come away with any sort of solid feeling anyhow. My girlfriend was doing a bit of research, but the primary hits for reviews ended up being from a subsidiary of one of the manufacturers...
So... Anybody got an undersink filter setup they're happy with? Any they hated with a passion burning so bright it couldn't be put out with the puny dribble from the craptastic tap?
