Product review (5 stars): This was a perfect item for my that purpose
I bought this to replace my Zuvo under sink water filter system for went out of business. I already had faucet and tubing from Zuvo so I only needed filter head and filter. This was a perfect item for my that purpose. I just removed the tubing out from the Zuvo and inserted in to the Culligan.  It took only 15 minutes start to end. Water tastes great (just like bottled water) so much better than Zuvo system. I also has PUR water Pitcher which I like but water from Culligan tastes equal or better than PUR.
