Review: Great tasting water - Our water tasted horrible. Decided to buy the Culligan US-DC3 direct connect under sink filter. Amazing what a difference it makes!! No more buying bottled water! Tastes great. I had a plumber friend install it so I can't comment about the ease of installation. For him it was pretty straight forward and didn't take long at all. I highly recommend this filter.
