Well, I got away without using a filter for 4 years living in NYC.
The Portland water is very good, but there is a slight chloramine aroma. So it's time to buy a filter.
This is a pretty cheap one I saw, what do you folks think?

I guess my only concern is if it will be a problem for this thing to sit around with water in it between brews. I think there are some other filter types, like the ones you can make a Randall out of, that you can take apart to dry between uses.
Or, any other suggestions on specific models?
