Product review (5 stars): I use it at Home and now at Work!!
I love these Culligan filters. I use one at home at my kitchen sink (extra nozzle). I bought this one to filter the water line that feeds to our water cooler at work. I'm an IT Director at work, but prefer to drink water that I know is clean; so I went outside of my scope a bit. It immediately made a taste difference.  (there are 2 activated carbon filters on the water cooler, but they only filter for taste, so I added this solution.)
